I have a curve with control points on which I'm going to instance spheres that are going to have shifting scale values (that is done) and hopefully shifting materials (and here I struggle). So I managed to add an attribute value (see picture) to the control points (vertices of the curve) that will control the factor in my mix shader for the material.
The problem is how to transfer (or assign) this attribute Value that is currently assigned to these control points), to my spheres instances (or the vertices of the realized spheres) that I’m instancing on that control points? Hopefully it’s clear what I’m trying to say. Thanks
