hi,
Can DR simulate a self-luminous wall or window? Can I create a new
luminaire, and define the self-luminous object as a luminaire?
I try to define a new luminaire in DR, but after I follow all the steps
in DR, I get the error which says "Couldn't open imposter geometry file
for parsing!". Can someone tell me a more clear figure to do this? or
tell me another way to create a new luminaire. Thanks a lot.
