  • Vray 3.5 Beta - RT CUDA crash to desktop when stopping render + black patches

    I'm getting dark patches on the image with RT CUDA. Also, when I stop the render Max crashes to desktop. Scene attached below.

    To test:
    1. Load the scene and render from the camera view with RT CUDA in Production mode (already set in the scene).
    2. A) Stop the render while light cache is still being calculated.
    3. B) Stop the render after LC is calculated and before the 2nd pass starts. So any time mid-render of 1st pass.


    Max will crash to desktop in both cases. I also noticed it doesn't crash if I stop it after the 1st pass is complete.

    Here's a screenshot of the strange patches while the same scene is being rendered (Only 1 GPU was used, no DR):
