direct/indirect lighting


Recommended Posts

Hello people

First I have to thanks to people who cover this site because of its useful. I can collect many info here.


It's the first time I post here, and my trouble is about radiosity! I link CAD file into VIZ4 and create all photometric light /w their IES files. But after starting calculate the radiosity (50% without filter or refine), direct lighting disappear on the ceiling (It's a direct/indirect linear light /w 80% uplight and 20% downlight, shadow is off). The first one was without radiosity, and with the left, radiosity was turn on.

How I revised that problem?




Many thanks in advance!
