Chaos Corona for 3ds Max => [Max] I need help! => Topic started by: Piotrek 3D on 2025-02-06, 04:38:25

I'm trying to create a scene, interior visualization and for some reason my materials and light change when I move the camera inside the room :/ I really don't know why this is happening and what to do: Everything becomes super reflective and white. I would really appreciate it if someone would be so kind and help me solve this problem.

It seems like whenever im close to window the results are ok but when i move a bit camera everything turns into white :/ Please help im clueless

Do your windows have thickness? (ie they are cubes, not just planes - the glass parts)
Does your glass material use any volume effects?
Do you have anything in the overrides in the Scene Environment section of the Render Settings (in the Scene tab)?
Do you have anything in the overrides section of the Camera settings?

This looks like a medium resolving issue.
The best thing would be to check the scene. For now, you can at least make sure the windows looking outside have simple glass material, without any volumetrics/absorption, and thin option enabled.

Yes, this can happen if Corona detects that you are inside a volumetric (including refractive) material. This may happen in some unexpected cases like having an object with no thickness (e.g. a plane) above or close to the camera.
Here, under "disable volumetric effects" you can find a script which removes volumetric effects from all scene objects. Please backup your scene and try it: https://support.chaos.com/hc/en-us/articles/4528592571537-Corona-renders-black-screen-3ds-Max
If it doesn't help, then most likely the issue is related to refraction without any additional volumetric effects. The solution would be to make sure that there is no object with no thickness using a refractive material in the scene. As Aram noted, it could be a window object using refractive glass instead of "thin" glass.
