Passing custom information to material from procedural mesh

Hey Deus0 - sorry for the delayed response, haven’t been checking the forums lately.

To use ColorComponent for tinting you need two things:

1. The line of code I gave in the other thread (now in the procedural mesh wiki entry) that copies the Color data for each vertex to the vertex buffer:

2. The material for your procedural mesh needs to pass that value to Base_Color or Emissive.

I actually use this pretty heavily while debugging mesh generation routines, myself. Here’s a typical screenshot, with the material editor open showing the Vertex Color routed to emissive:

Here’s the code generating vertex colors:

Hope this helps!

Ryvar, does ProceduralMesh Component already pass vertex color information? Or is it currently still broken and needs a recompile with your code fixes?

FWIW I already tried generating geometry with vertex color data and using it as base color and the data does not get passed correctly. From BluePrints the ProceduralMeshComponent only accepts a Color struct however BPs can only use Linear Color struct arrays as variables and there’s no way to convert from one array type to another, even with iteration.
