Using On A Render Farm
What render farm submitters need to know before sending jobs.
We could not inspect this add-on's code. Install it on your farm workers and run a single-frame test job before committing to a production render.
Scene Prep Checklist
Complete these steps before uploading your scene to a render farm.
- 1
Install the same add-on version on every render worker
Required - 2
Include all .blend asset files referenced by the add-on
Required - 3
Upload all external textures, presets, and asset files
Required - 4
Run a 1-frame test render on the farm before full submission
Recommended
Things To Watch Out For
- Local path or asset-library signals were detected. Paths that work on the artist machine can still fail on remote workers.
Common Mistakes
- Not uploading local assets or helper files, causing the scene to render incorrectly on the farm.
- Assuming paths on the artist's machine will work on remote workers without adjustment.
Recommended Workflow
- Check whether the add-on launches its own render operators locally and avoid assuming that workflow maps cleanly to farm orchestration.
- Open the scene in desktop Blender, run any interactive setup steps, save the file, then validate a small background render before scaling up.
Worker Node Setup
For render farm administrators: what each render node needs to run this add-on.
Install the same version of the 3D Print Toolbox on all workers. Ensure all external files and assets are uploaded with the scene.
