What you need
| Setting | Needed | What it is |
|---|---|---|
BLENDER_Environment variable | Optional | Absolute path to the Blender 3.0+ executable. Leave unset to discover it on PATH and at the platform's standard install locations. |
BLENDER_Environment variable | Optional | Ceiling for one Blender job in milliseconds. Renders and heavy conversions are the slow ones. Default: 300000 |
BLENDER_Environment variable | Optional | Directory for outputs written when a tool is called without an explicit output path. |
BLENDER_Environment variable | Optional | Set to 0 to withdraw blender_run_python, which executes caller-supplied Python inside Blender, from the advertised tool list. Default: 1 |
BLENDER_Environment variable | Optional | Ceiling on inlined image bytes. Past this the image stays on disk and the response says where. Default: 1500000 |
BLENDER_Environment variable | Optional | Longest edge of the render copy returned inline in a tool result. The full-resolution PNG is always written to disk. Default: 768 |
BLENDER_Environment variable | Optional | How many Blender processes may run at once. Further calls queue rather than compete for memory. Default: 2 |
THREE_Environment variable | Optional | Base URL of the three.ws deployment backing blender_forge_import. Default: https://three.ws |
THREE_Environment variable | Optional | Ceiling for one text-to-3D generation in milliseconds. Default: 600000 |
THREE_Environment variable, secret | Optional | Meshy/Tripo API key for the bring-your-own-key geometry lane. The default image lane is free and needs no key. |
