Hey there!

I really enjoy this mod, but how do I add entities from other mods to the list? They use the basic biped anim, so animating them as zombies / players should be possible.

How do I do this? The mod in question is Minecolonies.

Here is the bit where they render the citizens. Maybe that helps you tell me how to add them.

This will be possible with the new addon system I'm adding to Mo' Bends. You'll have to wait for the upcoming 1.0.0 version 🙂.
