Title: Reflections artefact with cr2
Post by: sa07kaiser on 2018-09-16, 13:48:22

Hello. Reflections on curved surfaces often become black, although everything is set up as standard. This did not happen before the installation of CR2. There is a solution? (look at vase on right side)

Problem was in background image. Diffuse - 0, self-ilumination enabled, global ilumination in rayswitch - disabled. Ok, but in new corona this leads to switching off the self-ilumination result in the reflections. I'm sorry to trouble you.

Can you reupload the image? I cannot see it.

Most probably it is one of the light transport issues when using fakes:

But it should happen in both v2 and 1.7...
