I use 3ds Max for quite a short time. I have problem with rendering light flat surfaces in my scene - there are dark stains on ligh flat surfaces. I took rendering setting and lights from my previous colleague - as you can see in prtscns. I use 3ds max mostly for rendering basic exterior scenes and I need the rendering to be as quick as possible with sufficient quality.
I would be vary glad to get some advice. As I've written, I am beginner, trying to learn more by myself, step by step.
If you need more info about my settings, please write here.
Thank you very much.
