It will add some crappy poses.
1. Open console.
2. Type "TFC"
3. Click or PRID to select PC or NPC.
4. Type PlayIdle pxx (xx = 01 to 93)
5. That's all.
(If you want to draw NPC weapon, select NPC and type "SetAlert" in console.)
You can play other animation while animation(like Umpa's one).
and you can also reset animation immediately by "PlayIdle Reset" command.
voila voila
