I am porting pre-existing lookdev, for assets developed in vray-3.60, over to vray-4.04.02. I have found that any materials where a ‘bump delta scale’ has been set to a value less than 1.0 is producing a very different result. Is this a known issue?
We don’t have a record of such an issue but I could see a small difference between 3.6 and Next so I’ll log it for investigation. It would help if you could attach a simple scene that reproduces it more clearly.
