You can even do a single hf combining several ones with more complex 
math functions (max and conditional functions) to generate height field 
and according color map. I'm currently also trying to generate a sort of 
finish map image.

I post an image of a wall I've made for my next IRTC, I'll post the code 
at the same time as my image. You can see that I have more troubles than 
you with the corner.  :-)
