Worked perfectly!

My HM was a bit too big to get any detail on the low poly mesh, so I had to blur it up a lot.
But this exactly what I wanted to do. Thanks for the help.

I've been making skybox sculpt meshes using Anvil and height-map displacements,
but I can't figure out a good way to paint the alpha on the sculpt mesh in a way that looks nice and won't take forever.

I'm using World Machine to generate the height-maps and textures,
and I've also generated a bitmap for the alpha channel based on face normals.

The only problem is I'm not sure how, or even if it's possible to apply a bitmap as the alpha channel on a sculpt mesh.

This is the sculpt mesh for a bit of context.



I temporarily changed the default grass texture to the generated bitmap alpha channel.
The final in-game texture should be a blend of grass and cliff faces.


tl;dr Is there a way to change a sculpt mesh's alpha channel with a black and white bitmap?
