I wanted to make a "+"-shaped pattern by overlapping a gradient x and a gradient
y pigment with abruptly changing color maps.
I seemed to get the first texture I specified in the layering - when I tried to
put a clear texture with an orthogonal stripe (0.49-0.51) on top of that, it
occluded the first texture.
I always have problems correctly implementing layered textures....
Gonna head to lunch - perhaps someone has advice / examples?
