The reason the elements are individually textured is that, though they may use
the same texture, the orientation of that texture is important w/r/t the
individual object, and cannot be placed on the whole model.
The problem is that I want to apply a series of overlays to the object as a
whole, to simulate the effects of age, decals, spray-paint etc... doing this to
individual objects would make the csg ten times as complicated - making it
impossible for me to construct the object procedurally, and use different
overlays for different situations - and involve complex transformations of
textures on the micro-level.
I've tried turning the image maps into isosurfaces and differencing them from
the object, but that's not working either because of sharp edges.
the only other things I can think of is constructing them as csg objects, which
would be tedious if not impossible, or "spraying" them on as microscopic
particles using trace and eval_pigment...
