I assume (but I may be wrong) that the macro calculates the proximity equaly 
in all three spatial directions. What you see on the image are the three 
used pigments in the pigment_map distributed by the macro more or less 
laterally from lower left of the building to upper right, which I find 
strange for a symmetrical object.

Try the 0.91 version of the macros I just posted to p.b.scene-files - hopefully
they will fix most of the problems you are seeing!

Cheers,
Edouard.

Edouard, Thanks indeed!

Now the macro works as it should. I have to play a bit now with the extra 
parameters to get what I want. I shall post results in due time, along with 
examples from other proximity macros I test to see which one gives best 
results for my particular project.
