Convert a texture channel to a Texture2D

Development Programming & Scripting

Hello!

I’ve been following along, but I’m a bit stuck. I’ve copied the function and I called it back into my material. And I’ve replaced the texture objects with my texture samples and that part works. but… I want to control normal map blending through vertex colours from height information, but unreal is being a bit of a pain. This is what I have:

Painting my objects with vertex colours have no impact, whatsoever.

  1. Can I not pull vertex colour information inside a material function?

  2. How can I get vertex colours to control the normalsFromHeightMap function?
