chipmatthews Posted October 16, 2018 Share Posted October 16, 2018 I render furniture for a living and I'm having a constant problem with V-Ray (3.6) when it comes to reflections on table tops. The back corner doesn't get any, and the closer the camera gets to coplanar to the top, the worse it is. This seems to be some kind of sampling problem but I've tried changing min/max values, light cache values, DMC type, light samples, and everything else I cant think of. Nothing makes a bit of difference. The only thing that helps is changing the BRDF of the material from Microfacet GTR and that just makes it less noticeable. The problem is still there. Does anyone have any idea what the issue is here and how to fix it? I always have to break out the clone stamp in Photoshop to fix the back corner after the fact. A sample image is attached.
