Figura mod: https://www.curseforge.com/minecraft/mc-mods/figura

When: If the player has a figura model equiped and they use any item with a custom animation like sun's blessing.
What happens: The player's figura model will disappear and the player will see a recreated default version of them doing the action, even in first person.
What I've done to try and fix it: Figura lets you create lua scripts for your model, they have had similar issues in the past with better combat but as long as you disabled some parts or the character model itself while in first person usually things work out. This isn't the case for this Mowzies so I'm unsure how to fix this.

Attached is a video on the error.

Hm. Seems like Figura is calling the third-person render event even while the player is in first-person.
I can't fix this...

You can disable Mowzie's Mobs player animations in the client config, or ask Figura to fix it.

Thanks, I'll also put up an issue on Figura's github to let them know about the incompatibility.
