so, I was using this as a mod in a modpack until my layers just randomly stopped working, I took it out of the modpack and now my head is stuck with 3d layers and I can't even take off the hat layer now

also, any skin I add it does the same thing

No clue what you mean by that.

So you still have the mod installed? If you dont want the hair to be 3d turn that off in the mod settings. That mc setting turns off the head layer fully.

I don't even have the mod installed anymore, that's the issue

If you can see it, the mod is still installed.

it's only on my head, the mod isn't on the version of the modpack I made, I removed every mod and you can even check the modpack itself if you don't believe me. The mod you made is NOT anywhere the modpack name is Save The World RP on curseforge

the legs layer is there without the 3d layers

I mean, check the mod list ingame. Either the mod is still installed, or it's some other mod like labymod that AFAIK has the feature just for the head.
