I have several images which I would like to
use as bump_map(s) on the same object. Is there
any way to combine those bump maps in a normal?
I need precise control on positioning those maps.
Thanks in advance!

Gena.

Untested quick idea:
Create a pattern function for each image and combine them in another 
function. Use this function as a pattern for your normal.

Or just use normal{average normal_map{...}}...

Does anybody have a working example with bump_maps?
Thanks in advance!
