Excessive Crunch Compression Blocking only on Box Filtered Closest MipMap

Enverex commented 3 years ago

Describe the bug

The closest mipmap on crunched normal maps appears to suffer from severe crunch artifacting, but only the closest mipmap and only when using Box filtering - Bilinear and Lanczos look fine.

Relevant issues

N/A

To Reproduce

Upload a normal map (not sure what's special about some that causes this to be more obvious than others).
Ensure it is crunch compressed and using Box (the default) mipmap filter.

Expected behavior

For there to be little to no visual artifacting.

What is the actual loaded variant displayed in the inspector for each of these?

Enverex commented 3 years ago

They all say "Format: BC3" and the VariantID below shows "Version 2, Compression BC3nm_Crunched, Quality 100, Mips True" for all of them, the only thing that changes in the VID field is the "filtering=" which changes to each of the respective mipmap filtering option selected.

Are these old textures or brand new? Can you give me NeosDB URL of one of them?

Enverex commented 3 years ago

New, only uploaded a week or so ago or so.
