01

Build in meaningful steps

Batch shapes and voxel edits into one transaction. Each committed step has a revision and an undo.

02

Give your agent eyes

Return actual PNGs through MCP. Inspect four angles without a window, display, or GPU.

03

Pick up where it leaves off

Connect to the native editor to watch changes, pause the agent, and refine the same model by hand.
