  • Walls always grey

    No matter what settings I enter I always end up rendering out these grey walls, then I want them to be a crisper white. Does anyone else have this issue?

    For a white wall you can start from something like 80% grey value, once your lighting/camera setup is correct you need to tune the tone mapping in the VFB, you can start with an highlight compression and use a photographic LUT or a filmic tone mapping to get a nice white wall while retaining a good contrast.

      White is one of the hardest things for me. I can almost never get it in the frame buffer, so I take care of it in post.

        Hi Bobby, you can get good white out of the VFB, here is an example, 80% white plaster, then just highlight compression and a LUT. Don’t forget that like in real life lighting, windows, and materials affect the result a lot, for example it will be very difficult to get the same white if your room have small windows, the sun in a different position, dark material on floor etc.

          Nice! What LUT are you using?

              Most problems with having nice whites, come from unrealistic values for diffuse / albedo, wrong lighting and camera setup. Using real world values and as Sirio suggested an 80% grey value should get you the results you're after.
