I finally found the problem:
This was causing the problem:
KinematicBonesUpdateType = EKinematicBonesUpdateToPhysics::Type::SkipAllBones;
This solved the problem:
KinematicBonesUpdateType = EKinematicBonesUpdateToPhysics::Type::SkipSimulatingBones;
I don’t understand how commenting these options in the constructor didn’t work.
I had to test all the options one by one from the blueprint.
It’s the price you pay for optimization.
On one hand you gain FPS and on the other you lose super cool things.
Well, I need the skeletal mesh ragdoll in the same place where the pawn dies.
This optimization is not useful for me then. Bad luck.
