If I understand you right, I think that was the first thing I tried. I set up an unbound PPV, and was able to tell multiple meshes to highlight one after the other. The problem is that they are all the same color based on what the weighted blendables are set to in the PPV. I couldn’t figure out how to do multiple colors that way.
Then I tried spawning a second unbound PPV with a different color and all the highlighted meshes changed to the new PPV color. So that’s how I found out that the meshes only highlight based on the last PPV that is spawned into the scene. Since both PPVs are unbound, the last one added dictates all highlighting to any mesh that is currently
->SetRenderCustomDepth(true)
So that’s why I’m trying to spawn smaller PPV volumes for specific parts of a mesh so they don’t overlap.
