Hi all,

I am relatively new to Povray. Usually I model in Blender and then render
with Povray via Blend2Pov.
Basically what I am trying to do is to create nice looking rust material.
Let's say I have base metal material, displacement image (lettering that has
to be embossed) and 3 layers of rust. All of that has to be blended together
via image masks I am going to create in GIMP.
I have tried to experiment with material maps, but I get really weird
results :(
I don't get smooth transition between materials.

Here is a mask:

And here is a result:

Can somebody help me and explain how to get smooth transaction between
materials please?
