With that said here's the copy paste of the post on the aforementioned site.
Okay after spending a lot of time doing research. I've put 75% of my knowledge into a tutorial format. It's a 9 page pdf and 15min video
explaining everything from getting the assets from Skyrim, setting up
your base file, modifying an existing animation and exporting said
animation.
This is not intended to be an all cumbersome tutorial that covers absolutely everything but instead to lay the ground work for existing
animators who want to get into game animation for Skyrim.
Also if anyone knows anything about exporting ragdolls for custom skeletons for skyrim please contact me. I'm trying to figure it out and any help would be awesome.
