Took me some time to figure out how to set the points color (“Cd”) attribute with data stored initially in custom points attributes. Hm alright I have it working to where I can put a solid colour on the geo with a color node and it will come though on the texture, so that's at least working, but for some reason outside my understanding, I just can't get the original colours from the points to come though the vertex attribute node and onto the material. The default shader in mantra, and many other shaders, will also use the attribute for rendering. Hi there, Noob question here. Extrude edges/faces.
