Normally when wearing the Elytra you can hide it with some mods by specifying to hide the "elytra" bone as per documentation here:

When I install this mod however both the Bauble and Chest version of the Elytra is visible even when hiding that bone. Could you please tell me what Colytra names the bone so I can attempt to hide it on my non-humaniod player model?

Edit: Skimming the code I see an event that renders the Elytra, I'm still hopeful there's a bone I can specify to just mark to now show. If not is there any other way to make the Elytra not show up while wearing it?

Thanks!

Update:

It appears it was Quark mod that was causing that unexpected behaviour for the chestpiece version of the Elytra. That works normally once I removed Quark mod after much searching. however the Bauble version of the Elytra still shows up when equipping so it appears to be identified as on a different bone. Any idea what bone the Bauble version of the Eltra is attached to so I can hide it?

Thanks!

Since you're using a mod to do the hiding behavior, this will likely need some compatibility between the mod that provides this behavior and Baubles. If they need to hook into rendering from Baubles, there's not much I can do on my end to help them. Also, "bones" is not a standard term so I'm not exactly sure what that refers to.
