In my game I’m trying to use texture splatting technique which allow me to have up to 5 textures on landscape chunk. For this I need to generate blend map so my game engine know how to blend those textures. I was googling a lot and found few tutorials describing how to mix 2 textures with one stencil. But I need to mix 4 textures and since I’m very new in Blender and design I’m experiencing few problems:
- For beginning I added 3 textures (grass, dirt and sand) and 2 stencils between them. But with this approach I can only draw sand on dirt, I cant add sand on grass because first stencil block it. It does change stencil but I can’t see sand over grass.

how can I solve this?
- At least I can paint on stencils and now I have to combine them to get one colored texture with each channel intensity of some texture. I was manage to achieve this using node editor:
but now, how do I export this to external image file so that I can use this blend map in my game?
Maybe in common I moving in wrong direction and there are better ways to generate blend map for 4 textures, while painting on landscape mesh in Blender?
