SkinnedMeshRenderer.BakeMesh() is baking ragdoll instead of animation

I have a character with animator and ragdoll. The goal was to copy his current model with animation applied by using SkinnedMeshRenderer.BakeMesh() . But it's copying it's "starting to fall" ragdoll state everytime I run Bake method. Despite model playing animation. Works fine if I delete all ragdoll related children with rigidbodies.
