I´ve been using Vray for a number of years, but this is the strangest issue I´ve encountered yet. Take a look at the images, and pardon the lighting conditions - I´m in the middel of testing this issue:
First image is normal lighting conditions - this is what I expect according to the light parameters.
This is where the strange thing happens - the ONLY thing that is changed here is that the door is open enough that its possible to see its backside, and the whole exposure goes to shit.
On the last picture nothing in the scene is changed whatsoever. I just moved the perspective viewport enough so that the doors backside isn´t visible anymore, and the whole thing goes back to normal.
All the pictures are in perspective viewport
The first and second image is an animation on the door while the perspective viewport stays the same. From the second to the third image the perspective viewport is slightly changed, while the door doesn´t move.
Please note that although I´ve tested different exposure settings, cameras etc, I´ve narrowed the issue down to wether I can see the backside of the door or not. Everything stays the same, but if I change the camera or perspective just enought to see the backside of the door (even if its just a few cm change of camera position) the exposure changes radically.
The door is normal, just like any other geometric part. It has a properly built backside, so its not the backside of polygons. I´ve also tried to collapse the stack, to no avail. Does anyone have any idea of whats happening here? I´m kinda lost, and have no idea why it happens. Although its a couple of years since I used Vray last time, I´m a pretty experienced Vray\3dsmax user.
