Short summary
MetaHuman bodies distorted / stuck in a broken pose (Convai_MetaHuman_BodyAnim, UE 5.6.1, plugin 4.0.0-beta.24)
What happened?
My Convai MetaHuman character bodies are distorted. They are all stuck in the same broken pose (one leg raised, one arm up) instead of animating normally. This happens with Convai_MetaHuman_BodyAnim on UE 5.6 in-engine MetaHumans.
I also get a repeated editor crash whenever I save or press Play. The conversation and lip sync still work, but the body mesh is visibly deformed.
It started after reinstalling the plugin.
What did you expect?
The character bodies should animate normally and keep their correct proportions, instead of being distorted and frozen in a broken pose.
Steps to reproduce
- Use an in-engine MetaHuman (UE 5.6) with Convai (BP_ConvaiChatbotComponent + Convai_MetaHuman_BodyAnim)
- Open the level or press Play
- The body mesh appears distorted and stuck in a broken pose; saving or playing sometimes crashes the editor
