I'm trying to use geometry nodes to make an ID map I can bake. I'll be baking in external software so ideally this would be vertex colour that can be exported in an FBX file. Applying colour based on UVs would be fine too, but I think vertex colour would be more straightforward.
How can I apply a different random value to the vertices of each loose part within an object? I cannot seem to find any Geometry node that allows me to affect loose parts of an object individually. I have also been unable to export vertex colours generated using geometry nodes.
