PD: if the black areas don't go away it is because the glass is reflecting a black area, maybe a black background?

David Bluecame wrote:Hello,
Thank you for your feedback. If possible we would need scenes showing the problems (with the textures used in them) so I can try to replicate the problem and (hopefully) fix it.
Best regards!

This is something I have to solve somehow. In the mean time there is a trick you can try: please try "clamp samples = 1.5" for example. This limits the intensity of each sample in the materials. Strictly speaking the illumination would not be "physically correct" when using clamping, but it can reduce noise and "fireflies". Please let me know if this helps for now.
