Loopcut Adds an AI Agent to a Blender Fork for 3D Editing

Developer Samffprice released Loopcut, an unofficial Blender 5.2.2 fork that can turn text prompts into Python code for 3D scene edits. The open-source project runs those scripts to make changes, but it is not affiliated with or endorsed by the Blender Foundation.

The agent can organize objects in a scene, fix normals, configure modifiers and lighting, and build rigs. Before each step, it shows the code and waits for the user's approval, though that check can be turned off.

Loopcut also captures the viewport to inspect its work. Users can attach a reference image for comparison, and each scene-changing step creates a checkpoint; restoring one returns both the scene and the conversation to their previous state.

Users can connect an Anthropic key or another OpenAI-compatible provider, run a model locally, or choose a Loopcut-hosted model. The hosted option has a free tier. Local models work offline, and requests made with a user's own key go directly to that provider rather than through Loopcut's servers. According to the developer, when using Loopcut's service, the project stores the token count for billing, not the prompts or scenes.

Loopcut has builds for macOS on Apple silicon and 64-bit Windows. The project's builds are unsigned, so users may need to allow the app to open the first time they launch it.

What kinds of 3D-editing tasks would you trust an AI agent to handle, given that Loopcut is an unofficial Blender fork?
