Best way to compress & optimize textures?

[Neyri LL]

I've ran into a problem with Cathedral Assets Optimizer, where the compressed textures end up having very noticeable green and purple blocky artifacts.

 

MY QUESTION IS:

 

• What other programs/workflows do you guys use to resize & optimise textures and other assets?

[mynewusername]

green/purple blocky artifacts is bad dxt textures compression, if you compress dxt textures, this happens especially on dark textures

Have you tried VRAMr? https://www.nexusmods.com/skyrimspecialedition/mods/90557
