I just install this mod in TLauncher and it works fine... when the sky is clear. when the weather in-game goes to rain, the raindrops texture was changed to my cape, creating this monstrosity:

pls fix it asap, my eyes are burning ;-;

Hmm, Which version are you using? Do this happen with only OfflineSkins installed?

i use fabric 1.16.5 and all the required dependencies are correctly installed. and this is the first time i use a fabric mod :/

I just tested using CurseForge, everything worked correctly.
Can you try it with other launchers? there are reports about incompatibilities with TLauncher.

yeah, i use tlauncher :/
and btw i forgot, i also use skinrestorer on my mohist server
