Shadow Catcher problem

Hello,

I have a problem with shadow catcher setup. Only way its working is shadow catcher plane and bright color in background environment slot. When I put behind shadow catcher bright light, bright dome light, vraylight material or put vraycolor to environment slot, its just not working and shadow catcher is pure black. Am I missing something? I want full white background and shadows on it, but I dont know why its not working. Scene is pretty simple, only plane and a sphere.

Thank you.

Shadow Catcher uses only what you have in the Environment slot - color or map.

Oh, ok. So what is the right way to make background completely white?

White in the “Color” or VRayColor in the slot.

I tried both. White color is not white in final render probably because camera settings. I tried disable affect background in Color Mapping, but didnt help. I looked for similar settings in camera, but cant find it.

When I tried VRayColorMap put in slot, shadow catcher object was black, didnt work with it in latest VRay 4.1.
