Process Background and Environment Maps option not working.

[kartaltur]

I am trying to match my model with a photograph. While i am using the exposure control on the scene "Physical Camera EC" or "Vray EC" still affecting the envrionment background on the render. I am using the VRay version 3.50.04 version.

There is an option in the "Color mapping" section of V-Ray (in the Advanced view) called "Affect background" - does it work if you turn it off? You'll need to use the "bucket" image sampler for this to work.

Best regards,
