I can't even begin to describe what a revolutionary, amazing, useful plugin this is. Having supported it's development from the start, I'm so happy to see where it is now. Ticxo is a damn legend for making this. It isn't the easiest thing, but if you get the hang of it, you can make some truly gorgeous mobs using this, that you could NEVER do with any other plugin.
Am running about 60 custom models all over 9 worlds on my Survival server. No lag issues, and have only occasionally seen some model part separation on various animations. Overall amazing product given what it does.
