If its possible to add compatibility for Eating Animation [Forge].

What part of it isn't compatible?
Been using the Fabric version the entire time just fine.

So I just tested it, its not the base mod its the addon "Eating Animations+". It think its a datapack but I don't know, its in the Resource Pack section in the CurseForge app. (Eating Animations+ by frogbirdd)

I mean, all they do is animate the item texture while it's getting eaten. That should work perfectly fine with the 3rd person animation.

Then I guess its the addon not having a 3rd person animation, thnx.

The eating animation plays when it's turned on, and the vanilla "eating" mode is enabled. So if some mod doesn't use that and implements their own stuff, that won't work.
