Important sampling problem HDRI lighting C4D-demo
Posted: Thu Jan 03, 2019 8:03 am
Hey.
I have been trying out the demo-version for Cinema 4D and I really like it. But I'm still a little bit concerned about the rendertimes/noisyness that can be a drag with these "unbiased"-renderers.
Anyhow, I have a strange problem now when I use a HDRI to light a car scene. When I have the "Imp.samp." unchecked the car renders pretty good but my groundfloor is suuuper noisy. So I click that checkbox "Imp.samp." and the floor turnes out great, but then I get a strange reflection on the hood off my car. Please see the pictures and I think it will make sence.

Can this be a bug for the cinema version, or can it be something with my car-shader maybe..?
Thanks,
Roger
