Title: Corona Sky with Volume effect + Overrides give gray stripe over the horizon line
Post by: Bormax on 2022-01-28, 07:54:18

Hi
Corona Sky with Volume effect + Overrides give some not nice gray stripe over the horizon line. If I rise the Altitude up to 5000m this stripe will be gone, but it affects the color of the "fog" which I don't want to change.
Is there any workarounds for this issue?
Is this limitation going to be fixed nearest future by Corona team?

Hi,
I found a solution.
Short bug correction instructions:
1. Set up a scene with clouds
2. Add a large Box to the scene going to the horizon line.
The height of the box does not matter much. But be sure to be above the line where the cloud clipping error occurs.
3. Assign the Corona Volumetric Material to the Box and adjust the Distance parameter (select the desired value based on the render). The color of the Scattering Color choose gray or white.
Watch more in the video.

Cool! I discovered it by accident. As a result of tests. I'm glad it works in C4D )
But we are still waiting for a fix from the developers.
