Animation Baker Pro provides packet conversion of humanoid animation clips into legacy or generic clips. I.e. you can retarget any humanoid
animation onto any humanoid character and produce new animation clip native to character's skeleton.Pro version has immediate conversion
function instead of realtime recording in free version of Animation Baker. Speed of conversion depends on power of your hardware so it is a lot faster and greatly saves the time. Also Pro version allows to create prefabs with characters and automatically adds created animation clips to it.
Free assets already included.
