Ensure condition failed: EditableBoneVisibilityStates.Num() >= OutRequiredBones.Num()

Hello.

I’m currently facing this weird error on my project. We have various SKs all of them working under a master skeleton asset (common biped character skeletal hierarchy + extra chains for clothes and that kind of stuff). One of the SKs for this extras (a handbag) consist on the same hierarchy as the master skeleton from root to chest + clavicle_L and the extra bones for the handbag.

CharFullHierarchy437×506 7.96 KB

Handbag_hierarchy
Handbag_hierarchy358×514 3.06 KB

We want the handbag to move with rigid body so for that I have this Postprocess_ABP.

HandbagPostprocess_ABP
HandbagPostprocess_ABP796×227 24.4 KB

This is assembled with the rest of the modules of our character inside a BP, being the Handbag_SKComponent children of the Main_SKComponent, which is the one it gets as the input for the CopyPoseFromMesh node.

The thing is this setup always pop this weird warning in the log the first time the character BP compiles in every session. Trying to debug it only appears when the rigid body node is connected as the output pose in the post process ABP.

We have same LODs settings applied to both Main Character and Handbag SKs but none of the bones used by the Handbag are removed at any LOD.

Any clue on this?
