Hi all!
I have a scene with an Arnold standard surface material with transmission set. Mostly, the render does what is expected, see the first image.
But sometimes, it renders the material as is the "Thin Walls" parameter is set to on, as seen in this image.
This is a problem since I'm trying to render an animation sequence. Does anybody know what might be happening? I tried to look through the forums, but I couldn't find anything. And btw, I'm using 3ds Max 2019 with the newest Arnold renderer.
