Horse animations toolhttps://www.youtube.com/watch?v=PZolKsvWH1M
IK pole vectors are not applied on this video, so you can see some improper positions
hrs0_main0_def.fmdl model must be in the same dir, tool needs it for bones.
fmdl_dictionary.txt has all known horse bones, 2 bone names are still used as hashes
- IK_TARGET_ ... bones are targets for nails (position+rotation)
- IK_pole_ ... (pole vectors) must be applied somehow
There is one additional rotation for each leg, thats supposed to set feet rotation, these are not extracted, because I don't know how to apply them.
