Hi, I believe this is the correct place to post this suggestion as I see in the Discord FAQ that suggestions should be posted in the Issues section for the mod.

I'm not sure which side would need to implement this, but my suggestion is for compatibility of this mod along with the More Player Models mod https://www.curseforge.com/minecraft/mc-mods/more-player-models) in order for hats to be shown on players using a creature's player model.

Reason: I recently just installed your Hats! mod and it is pretty great, and I've noticed the amazing compatibility the hats have in terms of being worn on the many creatures you find in the world. Sadly, when playing as a player model changed by the More Player Models mod, hats don't render on you nor in the Hats GUI. Therefore, my feature request would be to make it so that hats render on your player model as they do with the regular mobs you'd encounter.

Oh, and apologies if this has already been requested or explained why it wouldn't work somewhere. I looked around but couldn't find anything on it.
