Is it possible to do indirect lighting on wire? if so how, and can this also be applied if you have solid objects visible within the same scene?
I think wire material is not supported by ray trace engine yet, so no mirror, AO etc for objects with wire material only.
mesh line in blender are only one pixel wide so almost invisible
but you can make lines with curve and extrude circle or other shape
then you can size it and color it as you want !
i think is saw something in the composite to make lines appear colorfull too!
