I have a MaterialData plugin ,which is actually not supposed to be rendered with the c4d internal renderer, nonetheless gives a rough preview.

It works quite well so far but when GI is enabled it seems to emit light and illuminates the scene. There is no light at all in the scene and auto light is off, so it should render just black.

Any idea?

Thanks in advance!

Hmmm...

Am I supposed to provide the radiosity description interface suggested by the manual (as for the ogl preview size)?

Is the problem related to that?
