Changelog

What's new in 3D-Agent — new features, improvements, and fixes in every release.

2.1.21

October 1, 2026

New

  • The sidebar now shows which chats are working on a reply, so you can see at a glance which ones are still running.

Improved

  • The External agents page in Settings is now called MCP.
  • Checkpoints now use an updated storage engine with reliability fixes for your project history.

Fixed

  • Sending a message after your computer wakes from a long sleep no longer fails with "Your account couldn't be verified".
  • Long builds no longer stop with an internal error when the connection drops and reconnects.
  • When a reply fails partway, you can now Continue from where it stopped or Start over. Your work so far is kept, and interrupted replies are marked.
  • The password-reset link sent from the app now opens the page where you set a new password, instead of the sign-in page.
  • "Forgot password?" now confirms the reset email was sent and shows a countdown before you can resend, instead of a raw error message.
  • If the app couldn't reach our servers when you first signed in, your account now finishes setting up on its own once the connection is back, without restarting the app.
  • On Windows, 3D-Agent now finds Blender installed in a Steam library on another drive.

Thanks

  • Thanks to @rowdy1231 for reporting that Blender installed in a Steam library on another drive wasn't found.

2.1.20

September 30, 2026

New

  • New chats now run on our newest, most capable agent. Chats you already have keep the agent they started with.

Fixed

  • If your browser doesn't open when you go to checkout or manage your subscription, the app now says so and gives you the link to open yourself.
  • Sign-up and sign-in now retry on a shaky connection, and a network problem shows a clear message instead of "wrong password".

2.1.19

September 29, 2026

New

  • Attach as many photos as you like, at any size, as PNG, JPEG, GIF or WebP. Before, only four small photos went through and the rest were quietly dropped.
  • @video now has a settings bar with optional first and last frames.
  • @image can start from up to three source pictures, and generated images appear in the chat as they arrive.

Improved

  • Replies start faster, even right after reconnecting.
  • Blender actions run faster, without a fixed one-second wait on every step.
  • Heavy chats reopen in seconds instead of minutes, and long chats open straight at the latest message.
  • Stop is safer: the agent finishes cleanly, the chat keeps its context, and your next prompt runs straight away.
  • A stopped reply now says "You stopped this reply", and the note is still there after a restart.
  • When a chat gets too large, the message now explains why and that resending won't help.
  • Viewport screenshots are capped at 2000 px, so heavy scenes don't overload the chat.
  • The Plugins section is hidden in the app for now.

Fixed

  • Settings → App logs now shows your logs instead of "Couldn't verify your subscription".
  • No more "Reconnecting your session" screen after leaving the app open for a while.
  • Links to files in folders with spaces in their names now open and reveal the file.
  • A reply that gets retried no longer glues the cut-off text onto the new answer.
  • Several images requested in one message now all arrive.
  • A typed or pasted @image is now recognized.
  • Chats no longer lose their memory when plugins are enabled.
  • On plans without helper agents, asking for helpers no longer stops the reply partway through.
  • Boost replies survive a server update instead of asking you to try again.
  • Very large chats now send instead of failing repeatedly.
  • The Blender add-on now repairs a failed install the first time it connects.
  • Only one notice shows above the prompt box at a time.

Thanks

  • Thanks to @rowdy1231 for reporting the App logs window showing a subscription error.

2.1.18

September 24, 2026

New

  • New chats start on our newest and most capable agent.
  • Video generation now takes up to five reference images that you can @-mention by name in your prompt.
  • Add reference images by uploading them, dragging them in from your computer, or picking them from your chat's files.

Improved

  • Media inputs now sit at the top of the prompt box and also appear in brand-new chats.
  • Presentation Mode enlarges all chat text, types pasted prompts out naturally, frames renders cleanly, and keeps feedback buttons out of the shot.
  • The Hide scene thumbnails setting is now available in Settings → Interface.

Fixed

  • One Backspace now removes an @image or @video token.
  • When a reply fails partway through, the chat now shows the error and a Regenerate button instead of looking finished.
  • If your connection drops mid-reply, the app now notices within about a minute instead of hanging for five.
  • Losing your connection now shows a connection message instead of an internal error.
  • When a request is declined by the provider's content policy, the app says so instead of offering a retry that would fail again.

2.1.16

September 21, 2026

New

  • Presentation Mode makes recordings and demos easier with larger text, cleaner chat, and hidden account details.
  • You can now hide scene thumbnails in chat.

Improved

  • Thinking updates appear as separate, readable steps instead of running together.
  • Large prompts and image-heavy conversations are less likely to disconnect while uploading on a slow connection.

Fixed

  • The Plugins page no longer shows untranslated label keys.
  • Windows setup handles Microsoft Store installations of Blender more reliably and explains when they cannot be used.
  • Image attachment errors explain which limit was exceeded, in your language, without offering a retry that would fail again.

Thanks

  • Thanks to @Chris for reporting upload disconnects in large conversations.

2.1.15

September 16, 2026

Improved

  • Scene previews now appear as soon as your current view is ready, instead of waiting for the whole scene.
  • A finished preview stays on screen while you send your next prompt, so you don't lose what you were looking at.
  • Reloading a scene in Blender is more reliable, and when it does fail it says so instead of failing quietly.

Fixed

  • Previews no longer try to draw before the scene is ready to be shown.
  • An oversized reference image now tells you the actual size limit instead of a guess.

2.1.14

September 15, 2026

Fixed

  • 3D-Agent no longer offers to restart Blender when it cannot confirm what Blender is doing. A long operation that is still running stays marked busy instead of inviting a restart that would interrupt it.
  • Quitting the app in the middle of a turn no longer loses earlier replies and render images from that chat. A chat is now written whole, and one damaged by an earlier crash opens with everything up to the damage instead of refusing to open at all.
  • "View render" and "Saved Blender file" links at the end of a turn now open the file on Windows instead of doing nothing, and say so when the file has been moved or deleted.
  • Checkpoint cards no longer come out black after a long Blender operation. A blank capture is rejected and the thumbnail is taken another way.
  • A restart on our side no longer ends the turn you are running. The app waits the restart out and reconnects, instead of failing with "This request could not be safely continued".

2.1.11

September 11, 2026

New

  • Astra has landed.
  • Connect an external agent. Claude Code, Claude Desktop, Cursor, Codex and ComfyUI can now drive 3D-Agent over MCP, so you can build in Blender from the tool you already work in.

Improved

  • Agent settings are simpler, and a checkpoint restore now tells you exactly what it is about to restore before it does it.
  • Your prompt allowance can now carry a per-account bonus on top of your plan's usual cap.

Fixed

  • A chat no longer accepts a second prompt while it is still working on the first one, so it can't quietly overwrite the one already running.
  • The Roblox Studio plugin check no longer flashes a black console window on Windows.
  • Payment and other key action buttons now carry the same 3D shadow as the rest of the app.

2.1.10

September 1, 2026

Improved

  • When your Ultra boost ends, the notice now offers a "Continue on your plan" button, so you can keep working on the plan you already have instead of only being offered an upgrade.

Fixed

  • Plugin toggles now work in a new chat before you send your first message.
  • A chat that is still working on a request now says so and asks you to wait, instead of failing with a misleading "produced no output" error.

2.1.9

August 30, 2026

New

  • Connect 3D-Agent to Roblox Studio to inspect projects, edit scripts, insert assets, run playtests, read console output, and capture the viewport.
  • The agent can now see the Blender add-ons you installed, so it can use their capabilities directly.
  • Checkpoints now organize alternate attempts into numbered Takes, making it easy to revisit earlier work and move between attempts without losing the current scene.

Improved

  • When a task reaches its step or time limit, the app now explains that completed work was preserved and can continue in a new prompt.
  • Diagnostic uploads now retain the latest agent session details, making failed tools easier to investigate without including their command text or output.

Fixed

  • Windows: native tools launched by the agent no longer show disruptive crash dialogs.
  • Blender tools no longer fail with a false connection error when an installed plugin is disabled.

2.1.7

August 29, 2026

Improved

  • Diagnostic logs stay private. When you are signed in, the app now uploads them to your own secure storage instead of attaching them to error reports.

Fixed

  • Windows: prompts run and answer normally again. On the previous version a prompt could get stuck on "Thinking" forever, stalling before it ever reached the AI and leaving the app spinning with no answer and no error.

Thanks

  • Thanks to @cubano015 for reporting the Windows prompts that never got past "Thinking".

2.1.6

August 29, 2026

Improved

  • More of the app now appears in your language, including the General and Security settings pages.
  • The app verifies its built-in AI runtime at startup and automatically repairs damaged or tampered files.

Fixed

  • Windows: the agent can create and edit files inside your project again. Prompts no longer fail with "writing outside of the project; rejected by user approval settings", so paid prompts are no longer consumed by turns that couldn't save their work. The bundled agent runtime was upgraded as part of this fix.
  • The agent now starts with a clean environment, so credentials or settings from other software on your computer can no longer leak into or affect your sessions.

Thanks

  • Thanks to Ibrahim for reporting the Windows file-writing failures that were consuming paid prompts.

2.1.3

August 26, 2026

New

  • New subscribers receive the next plan tier for their first five successful paid prompts in the first billing month. Failed prompts do not consume a slot, and the app shows the remaining boost and when it steps down.

Improved

  • Installed plugins appear immediately while the online catalog finishes loading, with clearer actions, cleaner cards, and consistent primary buttons.
  • Roblox connections can be reopened without waiting for an abandoned browser flow to time out, and the callback page now clearly reflects success or failure.
  • Bundled plugins update automatically on app startup while preserving credentials, connections, and enabled state.
  • Account settings no longer show the standing “Open dashboard” button.

Fixed

  • Remote Blender extensions now install and enable correctly across supported Blender versions, including first-time repository sync and disabled online-access settings.
  • Blender commands now fail quickly with a clear recovery message when a reconnect is already in progress, instead of silently stalling the active turn.
  • Bundled plugins now install on Windows without an incorrect signature-mismatch warning caused by checkout line endings.
  • Plugin connection timeouts are treated as an ordinary unfinished flow instead of showing an error.

Thanks

  • Thanks to @Hugo for reporting the Roblox plugin connection and bundled-update issues.

2.1.1

August 24, 2026

New

  • Plugins are here: browse a dedicated shelf, enable tools per chat, and inspect each plugin before installing it. First-party plugins remain discoverable even when the online catalog is unavailable.
  • The new Roblox plugin can inspect and repair a scene, work with attachments and rigs, and publish through Open Cloud. Connect a Roblox account in one click, or keep using an API key for group publishing.
  • The agent can now understand images and Blender scene captures throughout the conversation, with image names and important scene measurements preserved end to end.
  • Customers in China can subscribe with recurring Alipay billing, including localized Card and Alipay checkout.

Improved

  • Billing and settings are now fully translated across all supported languages, including permissions, privacy, retention, and payment copy.
  • Upgrade prompts explain limits more clearly, payment methods are shown where they matter, and Card and Alipay choices have clearer trust signals.
  • The checkpoints panel is resizable, so scene history can stay compact or expand when you need more detail.
  • Plugin details are easier to scan, and model names are presented consistently without internal branding.

Fixed

  • Blender setup now repairs a disabled extension automatically, verifies installation on disk, and handles first launch on Windows without repeatedly reopening or misdiagnosing Blender.
  • Prompt connections are more reliable because refreshed credentials now converge correctly across gateway workers.
  • Windows installer bookkeeping no longer opens the full app during an MSI maintenance action.
  • Continuation chats created after the message limit stay inside the current project.
  • Composer controls no longer spill outside the chat card on narrow layouts.
  • Past-due subscribers are routed to payment recovery instead of a new checkout, and the Card/Alipay switch no longer appears on unrelated screens.
  • Roblox transform repair no longer damages the model it is fixing, and plugin credentials stay protected through deferred tool calls and external downloads.
  • Roblox setup now recognizes either a connected account or an API key, and its publishing guidance matches the account-first flow.

Thanks

  • Thanks to atamanchuk for reporting the Blender extension setup failure. - Thanks to jcjohnny5 for reporting the Windows first-launch setup issue and helping improve checkpoint navigation. - Thanks to trospix for reporting gateway credential instability and gaps in localized checkout. - Thanks to hcaumo for reporting missing payment-method choices. - Thanks to AgentPot for reporting continuation chats leaving their project. - Thanks to Aivaro for reporting the past-due checkout recovery loop.

2.0.34

August 15, 2026

New

  • The Permissions tab is now a one-click repair screen: it shows exactly what 3D-Agent still needs and fixes it for you, instead of leaving you to hunt through System Settings.
  • Blender can be restarted from inside 3D-Agent, and your work is preserved across the restart.

Improved

  • Signing in is immediate again — the roughly seven-second spinner after login is gone.
  • When a chat gets long enough to slow down, the warning now offers a plain "start a new chat" button right there.
  • The card that explains why a turn stopped is calmer and says what actually happened in plain language.
  • Scene thumbnails in checkpoints now match the colours you see in Blender instead of coming out dark.

Fixed

  • A corrupted saved session no longer breaks the app. Previously a single damaged file could make every prompt fail in every chat — surviving new chats, restarts, and even a reinstall — while the error promised a recovery that never happened. 3D-Agent now sets the damaged file aside automatically, keeps a copy for support, and carries on with your prompt. The file that stores your chat history also stays a healthy size on its own now.
  • The photo of your Blender scene stays attached to the turn that produced it, even if you navigate away mid-turn or restart the app.
  • File links in chat reveal the file on your computer instead of trying to open a browser.

Thanks

  • Thanks to Fastrix_Official for reporting the corrupted-session failure and sending us the damaged file, which pinned down the exact cause.

2.0.33

August 11, 2026

New

  • Apple Pay and Google Pay now appear as express buttons at checkout, so you can subscribe in one tap on devices that support them.
  • Drag and drop documents straight onto the chat box or a project's Files panel.

Improved

  • Pro and Ultra now use Extra-high reasoning by default; you can still switch back to High from the prompt box at any time.
  • Checkout is cleaner: a simpler header while you're signed in, and the fine print under the pay button no longer repeats itself.
  • After you sign in through your browser, the app comes back to the front on its own, and the browser page now has an "Open 3D-Agent" button to bring you back.
  • Very large requests are now turned away with a clear error instead of disrupting responses that are already streaming.

Fixed

  • Uploading documents works again, both in a project's Files panel and in a single chat: PDF, Word, Excel, PowerPoint, CSV, HTML, and text or code files are read and used as context, with a clear message when a file cannot be read.
  • Projects you create now survive a restart, and projects that had disappeared come back on first launch.
  • File links in chat now work: they render as real links and reveal the file in Finder or File Explorer, instead of showing greyed-out text marked "[blocked]".
  • Upgrading after a declined card now works on the next attempt instead of repeating the same decline for the rest of the day.
  • In plan mode, the chat no longer pins a photo of the Blender scene from an earlier turn; the scene photo appears once the work actually runs.

Thanks

  • Thanks to Alvaro B. for reporting the failed upgrade after a declined card.

2.0.32

August 2, 2026

Improved

  • Blender connection alerts now stay visible while Blender is disconnected, so a broken connection cannot be lost from view.

Fixed

  • The in-app log view and bug-report attachments now find the current log file again after an update, so problems can be diagnosed without extra back-and-forth.

2.0.31

July 25, 2026

New

  • Heavy chats now warn you before they reach the message-size limit, with a one-click way to continue in a fresh chat when the warning becomes urgent.

Fixed

  • Chats now recover from corrupted tool screenshots, and invalid Blender screenshots can no longer poison future messages.

2.0.24

July 22, 2026

New

  • After agent turns that change the Blender scene, a clickable snapshot of the result now appears directly in chat, making it easier to see and revisit what changed.

Improved

  • The **Checkpoints** control now lives beside **Plan** in the prompt toolbar, keeping scene history close at hand without covering the workspace.
  • On Windows, the Checkpoints panel now clears the minimize, maximize, and close controls, keeping its own search and close actions accessible.

2.0.23

July 21, 2026

New

  • Fresh chats now run on GPT-5.6 Sol, with High and Extra High reasoning plus native multi-agent and Blender tools. Existing chats keep their original model so ongoing work does not change underneath you.
  • When a chat grows beyond the model's history limit, 3D-Agent now explains what happened and offers **Continue in new chat**, carrying your last prompt over as an editable draft instead of leaving the conversation stuck.
  • After checkout, the browser now brings you straight back to 3D-Agent and refreshes your access immediately. Canceled checkouts also have a clear route back to the app.

Improved

  • The Checkpoints panel now uses a flatter, cleaner list, shows the open `.blend` file name, and keeps search tucked behind a button until you need it. The History chip also sits neatly inside the app edge instead of being cut off.
  • Hovering a **Checkpoint saved** chip now shows the date and time that checkpoint was created.

Fixed

  • Checkpoint image previews that could appear completely black on some graphics hardware now detect the bad capture and automatically try a reliable fallback.
  • The pricing-page logo carousel no longer flashes, jumps, or scrolls blank logo slots into view while images load.
  • Message edit, delete, and regenerate controls are now correctly hidden in production builds.
  • Expected Windows connection resets during agent shutdown no longer generate misleading error reports, while real connection failures remain visible.

Thanks

  • Thanks to Epir for reporting the large-chat failure.

2.0.22

July 20, 2026

New

  • Checkpoints: 3D-Agent now automatically saves a checkpoint of your Blender scene after every turn. Open the new History handle at the chat's edge to see what changed each turn, search by object name, and restore any earlier version with one click — your history never leaves your machine.
  • Variations: ask the agent to build variations of your scene and switch between them without losing progress — each set appears as cards right in the chat and in the History panel.
  • "When did it break?": the agent can now walk back through your checkpoints with you to pinpoint the exact turn where something went wrong.
  • A new Settings → Checkpoints page shows how much space your scene history uses, with a health check and storage controls.
  • Rate any result with a quick thumbs up or down — a thumbs-down offers one-tap categories so the agent learns exactly what to improve.

Improved

  • The agent brings specialized know-how to 13 kinds of Blender work — 3D printing, game assets, characters, rigging, architecture, product design, jewelry, vehicles, furniture, weapons and props, scenes, texturing, and logos/text — for better results in each.
  • While Blender connects, the banner is clearer: links look pressable, the "connects automatically" reassurance leads, and a brief "Connected to Blender" confirmation appears when the connection recovers.
  • Catalan, Czech, German, Spanish, French, Hindi, Indonesian, and Japanese caught up with English — hundreds of previously untranslated strings per language now show in your language, and a few dialogs no longer display raw formatting code.

Fixed

  • On some machines the message box could stay locked with no explanation when 3D-Agent couldn't check Blender's status. It now shows the "Searching for a connection with Blender…" notice with one-click actions to open or download Blender instead of staying silent.

2.0.20

July 12, 2026

Improved

  • Blender connection messages are calmer — instead of a red error card, you now see a quiet loader with a clear next step (an "Open Blender" link, or a download link when your Blender is too old) while it connects.
  • Chats packed with Blender screenshots are faster and more reliable — screenshots now travel in a lighter format, so image-heavy conversations no longer stall or fail.

Fixed

  • Hitting a step limit now shows a calm check-in card instead of a red "internal error" — and continuing no longer re-charges your whole turn.
  • Pressing "Continue" after the agent pauses (a step limit, a retry, a cancel) now resumes your real conversation instead of forgetting everything and starting a blank one.
  • A brief connection hiccup no longer kicks you to the full "sign-in no longer authorized" screen — you now see a quick "Reconnecting your session…" that clears itself.
  • Selecting Català now actually switches the app to Catalan.
  • Code blocks stay left-to-right and readable even inside Arabic or Hebrew replies.
  • A single misbehaving extension can no longer blank out the whole app while it loads.
  • Messages no longer occasionally disappear after a reload when an edit and its creation arrive at the same time.

2.0.19

July 9, 2026

New

  • Reference a Blender scene object right from the chat box — type `@` to mention a specific object (like `@Car Body` or `@Camera`) so the agent knows exactly what to act on.

Fixed

  • Long, heavy chats no longer fail on every turn — very large conversations now go through reliably instead of getting stuck.
  • Opening 3D-Agent while Blender is already running no longer flashes a false "extension not responding" error — you now see a calm "Searching for a connection with Blender…" loader while it connects.
  • Canceling your subscription from the billing portal is now recognized correctly, so your plan status stays accurate.
  • The assistant no longer slips internal codenames into its answers when you ask what it is.

Thanks

  • Thanks to etwin30 for reporting the large-chat failures.

2.0.18

July 9, 2026

Fixed

  • Fixed the recurring "Connection interrupted — Retry" outages that could stop prompts from responding — the connection now recovers on its own and stays stable.
  • Your plan no longer briefly flashes as locked when your session quietly refreshes in the background.
  • Your subscription status now stays accurate as your billing period changes, so an active plan keeps working the way it should.

Thanks

  • Thanks to G. Lima for reporting the subscription status issues.

2.0.17

July 7, 2026

New

  • Watch the agent think: its reasoning and plan now stream in live as it works through your request, so you can follow along instead of waiting on a silent screen.

Improved

  • The activity shown while the agent works is calmer and clearer — reasoning takes center stage, the distracting elapsed timer is gone, and repeated status lines are collapsed into one.
  • Prompts recover more smoothly when the service is briefly busy or your session needs refreshing, so momentary rate limits cause fewer interruptions.

Fixed

  • A reply that was still arriving when your connection dropped is now delivered instead of being lost.

2.0.16

July 6, 2026

New

  • A live activity card now shows what the agent is doing during longer turns — a working indicator, an elapsed timer, and the steps it has finished — so you can tell real progress from a stall.

Improved

  • Plan cards on the dashboard now match the app, with full feature lists, plan badges, and clearer upgrade options.

Fixed

  • Opening the app with Blender closed no longer briefly flashes the wrong Blender message before settling on the correct one.
  • The app now connects reliably on networks that inspect secure traffic (corporate proxies, antivirus HTTPS scanning) that previously blocked sign-in for some users.
  • Sending a message now jumps the conversation to your newest message, so you always see it — and the reply start — even when scrolled up in history.
  • Pasting text that's too long for the model now shows a clear message right away instead of quietly retrying several times.

2.0.15

July 5, 2026

New

  • A "View Changelog" button now appears when an update is ready, so you can see what's new in each release.

Improved

  • Prompts respond faster and stay responsive during long, multi-step tasks, thanks to a new real-time streaming connection.

Fixed

  • Reaching your plan's step limit now shows a clear check-in card — keep going or upgrade — instead of a confusing red error.
  • Chats that used to get stuck showing an "internal error" on every message now recover on their own and keep working.

2.0.14

July 4, 2026

New

  • In plan mode, the agent now asks clarifying questions right in the chat before it writes a plan — pick an answer or type your own, so the plan matches what you actually want.
  • Answering those plan-mode questions is free and never uses a prompt credit.
