The tutorial on the wiki explains this process pretty thoroughly: http://wiki.tesnexus.com/index.php/Working_with_animations_in_Skyrim I've been able to convert the .hkx animation files to .kf and import them successfully into max 2012. The export and conversion from .kf back to .hkx also works correctly. The animations I've tried (walk and run animations) work in game, but there are strange problems like the weapon sticking through the pc's body or the head compressing down into the neck. I'm not sure if those problems are related to the import/export process, the conversion process, or something else. Good luck. Thanks, man. I`ll read later. I created character rig (CAT system win Z axis orientation - http://skyrim.nexusmods.com/downloads/file.php?id=11434 ) and I want to see what happens in Max with my charaters. I used a biped skeleton from MakeCG, but at the end of the work I desided to create my own. Now I`ll see what realy happen with Skin in game. Here is my blog for skyrim, sorry it is in russian, http://3694.blogspot.com/search/label/Skyrim
