well, i cant help, but i can tell you that JME 3.* have different animation system and i think its because MonkAnim 2 is not compatible with JME 3.*.
seems like need update you with JME news
Anyway most of MonkAnim features you could do with JME 3.* new animation system + Minie project. MonkAnim seems to be dropped(since i dont seen author(Nehon) posts a long time).
so like i say, currently Minie is supported one and anyway JME 3.* should itself have already some of MonkAnim features too. (mixing anims/etc)
as i know MonkAnim 2 was created by Nehon for older JME versions, but Nehon decided to create something even better(so MonkAnim is deprecated overall - also because Nehon is not responding, he disappeared), so he made new animation system (no name?) for JME 3.* that is already there(you can use it). So you dont really need MonkAnim v2 there, but you will be lack of some features like softBody (that is in Minie that works with JME 3.* and is supported)
Ye, okay. We’re on the same page now haha. Well the Armature is deforming the meshes in a crazy way. Almost like theyre reversed. But I’m not sure where an error on my part could cause this issue
