I noticed there was an EpicFight addon mod but not one for BetterCombat. Is that something you had planned for the future? If not, that'd be my request. Generally support for playerAnimator and bendylib stuff so that when the Humanoid NPC is running around or attacking it looks nicer. The passive poses from things like SimplySwords should also work too if that's done

Thanks for the feedback. This is something you need to check with the BetterCombat mod developers.

The EpicFight mod supports the animation for a set of entities and models.
See: https://github.com/Yesssssman/epicfightmod/blob/78b69b575d8953f44538cd5b312768a1e07f392b/src/main/java/yesman/epicfight/api/client/model/Meshes.java#L45-L64

The BetterCombat mod however only supports PlayerEntities.
See: https://github.com/ZsoltMolnarrr/BetterCombat/blob/1.20.1/common/src/main/java/net/bettercombat/mixin/client/AbstractClientPlayerEntityMixin.java

As long they are not supporting non-PlayerEntities there is no way for me to integrate such mods.

there is a new mod that can maybe can help you with code it https://modrinth.com/mod/better-mob-combat
