Height map in alpha of terrain texture

Development Asset Creation

I am putting the heightmap into the alpha channel of the terrain textures and use a LayerBlendNode to blend between them based on LB_Heightmap. But it seems UE4 doesn’t like that, since the material is black and the layers don’t show up in the “Target Layers” menu.

Why? Is there a way around that (apart from keeping the heightmap as a separate texture)?

Hi ,

Can you post a screenshot of what you are trying to achieve, I’m a little confused. Thank you!

Forget it, I got it working, must have been doing something wrong… Just for reference, what I am doing is:

  1. Use a LayerBlend node to blend 4 terrain layers.
  2. Import a layer weight texture into each layers’s info object.
  3. Height blend the textures using LB Height Blend, where the textures heightmap is in the alpha channel of the diffuse
