Well after finishing that last reply, I realized that I wasn't actually finished with my code. I continued to add a third pass for a Dark Grass texture and it all went crazy. almost like there was a bloom effect of the textures. So, I started doing some research into the MultiMaterialShader and it isn't exactly what I thought it would be. And it would require a lot more to start combining multiple layers more than just the 2.

So I am currently working on a hybrid version of the GLTexCombineShader of my own to allow for, Material1, Material2, BlendMask images and it will give you the combination of those two. I then plan to use this mixer again with every output per layer of mask and texture I have to add. I am hoping that this will result in the effect I am looking for.

Any suggestions or directions for help are welcome.

Thanks,
