Separate value for each vertex for instances?

[Evgeni_Popov]

Welcome aboard!

It’s not possible to have per vertex per instance data using an attribute. You can do it using a texture that will lookup the data by using the gl_VertexID / gl_InstanceID predefined variables. See for eg:

Using .glb model with instantiation and vertex colors

I don’t think you will be able to change the color of each vertex for each instance easily. As @Deltakosh said, there’s a way to set a color per instance (so the same for all vertices of the instance) but not to set a color per vertex per instance. You could do it by using a custom shader and using the gl_VertexID and gl_InstanceID predefined variables to lookup the color you want in a texture you would create in a pre-process and pass to the shader.
