GI Compositing

Here you g, this is Kramer’s tutorial on using omni lights in an array to replicate GI almost perfectly. It’s pretty close. It only becomes noticeable once your output resolution reaches about 4k, and i dont see why you would be rendering 3D footage at 4k so you should be fine. Good luck!

Thanks for the link. For Andrew’s problem the light dome worked well. Not so much for car paint in a scene where both car and camera are moving. The paint has to reflect the “sky” and still “sit” on the road. And to move a dome of 40 or so lights that is dependent on the same camera angle isn’t quite as easy. I had tried using Tim Claphams light dome https://www.helloluxx.com/cinema4d-mograph/cinema4d-light-dome/which is really cool for stage setting but not for a moving object.

What was interesting in Andrew’s demo was the tacit admission that GI flickers in Max as well in low GI settings. I had gone to 30 hours (mostly mid level settings with high stochastic) but maybe it requires throwing the book at it to get the true look of animated GI. Try going to https://www.suurland.com/ and you can see what I mean about “sitting” a car. Somewhere on there he has a movie that he did and when I grow up I want to be like him. Maybe it just means stupid amount of rendering time and the 1 minute cool still is just a tease for one hour a frame for the big time look. Or maybe Vray can do it. They certainly have nice animations.

Anyway thanks again.
