Features of "Ears" mod stop working if "OfflineSkins" is installed. Everything works, just without any "Ears" features. I've read few similar tickets. However, they were talking about using a skin from the resource pack. Here it's kinda similar, yet different situation. "OfflineSkins" allows skins to work on a server with online-mode=false. So, right now on such servers, there is really no way to see any of "Ears" features. So, would be nice if "Ears" supported "OfflineSkins" in some way.

Minecraft 1.20.1
Forge 47.2.20
Ears 1.4.6
OfflineSkins v1

I second this! I often play offline and use a resource pack to turn the default skin into me, but Ears doesn't work with that either.

You can use Selfskin! it's compatible with Ears!

Oh, never heard of it before. Just tried, works perfectly and even launched on Forge through Sinytra Connector! Thanks!
