To get the colors from the point cloud onto the polygonizer mesh, you need to do something like this:
- On the polygonizer mesh, create an ICE Tree.
- Use Get Closest Location to get a location on the point cloud, get the color from that location.
- Store that color somewhere (eg in an attribute on the polygonizer mesh, or in a vertex color map).
Here I’m storing the colors in a CAV:
And here I’m sticking the colors in a per-point Color attribute:
