Title: Problems with the reflection
Post by: julius_saurus on 2021-04-05, 09:36:28

Hi guys,

I've been having this problem in one of my projects. For every reflective material with the glossiness below 0.90 there is this black spot. I found out that the problem just happens when I have the curtains in front of the windows (the light source). It doesn't matter if I use Corona Sky, Sun or just Corona lights, the black spot is always there. I tried to merge the scene into a new file but nothing happened, what else can I try?

I'm using Corona 6 and 3Ds Max 2020.

I thank you guys in advance.

Julius

Hi,

This is known issue, look for the "black highlights" section in this article: https://coronarenderer.freshdesk.com/support/solutions/articles/5000516180-known-bugs-and-limitations
