No, I believe that’s not allowed only the in-game costumes.

thanks

There are a couple character skins I'd like to use for the speed runs, such as RE-themed skins for Leon and Ada. Does anyone know why it's not allowed?

my guess for the reason is that some of the skin mods have gameplay related changes, example being knifing animations being different

It's less the above and more that skins can change how hit boxes and what not work, and even if your skins don't, then the mods have to come up with a list of banned mods and that is a ton of work. But, RE3R now allows skins so it's possible that they could change it for RE2R as well, you'd have to ask the mod team though.

shaders are allowed skins are banned without any kind of test btw, you can just bring it up

shaders are banned as well

hmmm banned out of nowhere i see

Is HUDSight allowed?
