This one is for more advanced users. The file sorts rather big “Unknown” tab into proper categories.
You won’t see effect immediately on existing sessions. You’ll need to right click on relevant models in animation set editor and pick “Rebuild Control Groups” option.
Usage: put this file into “Your SFM Folder/game/platform/cfg”
Warning: this will naturally replace your animation groups file. If you modified it extensively on your own all changes will be lost. So, always backup the original file!
