Hello,
I have a problem which I can’t get rid off. I made a simple rectangular glass with one extrusion. I am using V-ray for rendering and there is so much noise behind in the shadow of the glass and I don’t know why. I have set up the sampling subdivs of the light to 32 and threshold to 0.001 but it seems it plays no role.
Below are the pictures of the glass and the settings.
Also there are some strange reflections on the edge of the glass - its rendered inside a cube with flipped normals and with only 1 rect light.
Any help will be greatly appreciated.
