I’ve been using mental ray quite a lot for my job (im an interior designer not really a 3d artist).
i’ve been using the same settings for months to get the right global illumination when yesterday this happen.
I have been using the same setting for a very long time and i can’t explain why.
i have increased wall thickness and decrease sample size radius and it kinda worked but iwas just decreasing the sizes of the balls icreasing a lot the render time
anyone can help pls? <3
