Serializes soft body nodes (vertices), links, faces, tetrahedra, materials, anchors with rigid bodies.
Some todo's are serialization of pose, constraints between soft bodies
Add flags to disable bvh and triangleinfomap serialization
btSerializer::setSerializationFlags(flags)
flag can have value BT_SERIALIZE_NO_BVH, BT_SERIALIZE_NO_TRIANGLEINFOMAP
So it is different from the in-place method (btQuantizedBvh::serializeInPlace/deserializeInPlace).
It is also possible to serialize/deserialize just the bvh, using the btSerializer (needs some code snippet/helper)
