Denoise Problem behind Glass
Posted: Sat Jul 11, 2020 8:08 pm
I had this problem before and posted in the Standalone area ( as it does occur to it too ) But received no answers and I thought I managed to solve it but Nope..
I have a nasty denoise problem with textures behind a glass, I did try almost everything from a simple plane to a thick polygon BUT even at 3000 samples the result is pretty unusable, attached 3 images were the blurred one is a denoise pass with a glass in front of the texture used for the frame but I have the same with a texture behind a shower glass, I don't know if I have to uncheck or check something BUT is just something I did not expect now as I'm in a middle of delivering some work.
Images are 1000 samples PT

and I still think there is something wrong with the specular material? OR I totally lost touch with the Engine for some reason but have a look at this file, I used a plane with specular, the middle one is fake glass material and the right polygon is with thickness still both specular are behaving more like a metal to me that a glass?
