Title: CBitmap - environment blur issue
Post by: romullus on 2023-10-10, 14:55:32

3ds Max 2024.1 Corona 10 HF2

If environment texture is loaded through Corona bitmap, then its filtering blur is affected by the extents of the scene. The issue is not present when environment is loaded through Max bitmap. Video and the simple scene are attached to the post.

Hi romullus,

Thanks for reporting this.

Does this happen only to the reflections, or the background/refractions are affected too?

I think it's affecting background too, but i didn't test refractions.

EDIT: i did couple more tests - it looks that background and direct visibility override are not affected, everything else are affected by this issue.

Update:
There has been a major feature update - Differential Ray filtering - which solves this issue. Meaning scene extents do not affect the blurring/filtering seen through reflection/refraction.
Old scene will have the options (differential ray filtering) disabled, so they should be affected. Turning this option ON (this is the recommended state and new default) should solve it.
Upcoming daily build will have this feature in it.
