[Radiance-general] mosiac with mixpict? (was: Re: Transparent Textures in Radiance)

Sorry, first thank you for the reply, but I had better changed the 
subject line (I didn't because I wanted to add to the old thread, which 
was about transparency and mixpict, showing mixpict useage by an 
example). I don't want to map on a transparent surface, but an opaque 
one, to describe a mosaic. If I used the void modifier, I think I would 
have to model three surfaces, so that each surface takes one material 
modified by the mixpict "mask" - that doesn't sound very reasonable to 
me. So the question is still if I can use a mixpict-modified material 
as background in a mixpict modifier's definition, some kind of nested 
mixpict modifier.

Thanks+CU Lars.
