R3

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

What Claude can build: 3D scenes with materials, lights, fog, terrain and HDR environment lighting; tileable texture sets (colour, normal and roughness maps) from procedural recipes such as gravel, sand, concrete and bricks; physics with rigid bodies, colliders, joints and drivable vehicles; keyboard, mouse and touch controls; positional sound and music from beats, drum grids and patterns, with visuals that move on every beat; camera moves such as a chase camera; a help overlay that lists the controls. 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 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 and press Allow. By default Claude may delete only projects it made itself and never published; going live, deleting your own projects and assets, and changes to your Blender models stay off unless you tick them on the sign-in page, and Claude asks when it first needs them. You can disconnect at any time under Settings → AI & apps → Connected apps.

The connector carries R3's own guides, so Claude reads the R3 API before it writes code.

Free account. One project can go live for free; paid plans allow more.
