ZFact Posted May 23, 2006 Share Posted May 23, 2006 Hi all; Im just wondering should i be using the compositing tag to turn off GI on certain elements in a scene... such as trees and planting. The min and max red and green dots seem to be getting distributed over alot of planting rather than on the actual building in question!! Link to comment Share on other sites More sharing options...
Ernest Burden III Posted May 23, 2006 Share Posted May 23, 2006 Yes, you should. I like to keep 'recieve GI' on in the material's Illumination pane, but you should comp. tag stuff like that, and glass, and small mullions, as to be 'not seen by GI' to save some time.

Or, you can put in a special ambient light that only affects them by listing those things in the 'include' pane in 'scene' for the light. You're getting into faking things that should work without faking, but I'm not finding C4D's GI engine up to the task, so fake away. Link to comment Share on other sites More sharing options...
Sindala Posted May 23, 2006 Share Posted May 23, 2006 yup, fake away. one thing i ofted do lately is assing objectbuffers to the faked objects so you have an easy way to select them in photoshop lateron. that way you can adjust and finetune them easily.
