I’ve been trying to animate my Metahuman with live link for IOS and I have encountered some errors I have never worked with before.

This appears when I simulate the Metahuman. I’ve tried replacing nodes, using csv files instead of live, multiple hours of google searching, and even reinstalling the engine since this has worked before on another computer of mine. The full error code is as follows:

Blueprint Runtime Error: “Failed to resolve the subject. Be sure the subject name and role are valid.”. Node: Evaluate Live Link Frame Graph: EventGraph Function: Execute Ubergraph Face Anim BP Blueprint: Face_AnimBP

This makes my Metahuman not work in simulation. It is being casted into the animation blueprint fine but it just wont simulate. Does anyone know how to solve this?

i had this problem. figured out that i force deleted a meta human and it changed something in source blueprints. i migrated my scene to new project and redownloaded meta humans, and it worked out.
