Title: strange red reflections
Post by: gpz on 2018-03-21, 15:42:03

Hi
i got some problem withe reflections.
I have a scene with some cubes in the celing  with a gold material and some light among the cubes.
Then when i render i get this kind of artifact: some red reflections.
Any suggestion to solve the problem?

Thanks

Can you post a higher resolution image? I can't see whats going on.

*Edit: Also probably a good idea to post the offending material in slate mode  for some more info.

A quick thought in passing - are there any non-Corona materials in the scene? Was anything imported that used another render engine? The "Material not supported" color in a render is a strong red like this one, if the reflections are reflecting that, could be what you are seeing?

Hi ,
sorry to be late answering but i was very busy.
Anyway. I checked geometry and materials. Everything seems ok.
I think there is no artifact. I suppose that is a kind of a strange behavior of the material (gold) due to ping pong bounces of the light and the reflections in combination with distance from the camera.

Yeah, one idea to check it would be to take the reflection color and slightly move the saturation slider - does it change then?
