Hello, long time ago mentioned this on some chats and probably forgotten, here is topic reminder and repro resource.
Quote of response from chat which might help maybe
the skin tone draw pass likely has a fixed target size
if lucky this is one of the few places where game code does the dxt compression stuff it does so it’s easy to find where this comes from
Currently every drawable that ends with “_r” (which enables ability to change skin tone) has compressed(?) texture automatically by GTA. Picture below as a comparison between _u and _r
Unfortunately I wasn’t able to reproduce it on some random ‘box’ with random texture, only on some converted clothing from other games. As a reproduction I’ve made these pants in few minutes
