R3

R3 is a browser platform for interactive 3D: scenes, physics, audio and music, built from components, with Blender .blend import. This connector lets Claude work on your R3 account.

What Claude can do: list and open your projects, create new ones, add objects from factories, read and set component properties, and write the code that makes things move, collide and make sound. It can import your Blender models, make a preview link to share, and publish a project live as a release you can roll back. If you have R3 open in a browser tab, Claude edits that project live while you watch, presses Run, reads what the scene is doing and can take a picture of it. Your own edits and Claude's go through the same checks, and code is version-checked, so neither of you overwrites the other.

How it connects: Sign in with R3. You sign in (or create a free account), see which app is asking, choose what it may do (read projects, create and edit, write code, run in your editor, use your files, make previews) and press Allow. Deleting, going live and changing your Blender models are off until you allow them; Claude asks again when it first needs them. You can see and disconnect the connection at any time under Settings → AI & apps → Connected apps.

R3 reads documentation first: the connector carries its own guides, so Claude learns the R3 API before it writes code.

Needs a free R3 account. Live projects need a plan; previews are free
