I am new to setting up shaders for Unreal. Can someone point me in the right direction on how to set up a mask to only allow Subsurface color to work on the leaves on my branch…not the bark.
I have the bark masked out in Photoshop but I don’t know where to attach it in the shader.
Also adding in another texture for a mask is going to pull performance down. Can I just pack this new texture mask into the Alpha slot in my normal map texture? As my regular diffuse texture has the full alpha already packed. in.
