Material ID Export · Material ID

Control	Effect
Output	Folder for the exported files. `//` is relative to the blend file. An unsaved file falls back to Blender's temp folder.
Depth	8-bit (normal) or 16-bit (immune to dithering, heavier)
Crisp Edges	Render the ID pass with anti-aliasing off. Leave on for Photoshop selection.
Render ID Pass	Render only the ID pass and write the PNG
Export Swatches	Write the `.aco` and `.csv`
Add File Output Node	Optional: add compositor nodes so the pass is written on every normal render
Remove ID Nodes	Strip everything the add-on created

When Depth is 8-bit and the scene's dither is above 0, a warning appears with a button to set it to 0. Render ID Pass handles this itself; the warning matters if you are exporting through your own compositor nodes.
