Issue with Player models shading and stuff :)

OK so i am having some issues with my server. not sure how to fix it. here are some screenshots. not sure what is the cause. i’m thinking a shader issue maybe. let me know if anyone else is having the same issue :slight_smile: thanks

The telletuby is supposed to be purple. instead i am either getting a green tint or random color shades (normally dark).

The map is causing it.

Is there a way to fix that? it does it on a lot of maps. and for example, Minecraft b5 does it as well. and it does not do it on other servers.
