Thanks for the answer though, they didn't write anything back even on the developer's forum yet..

Well, they don't tell which bone to assign the belt actually, and there is no real "belt" bone, so i went for the closest, tried several others, but even if i am still at the wrong bone, WHY is the basic test model of witch doctor differ, from the basic model which you can see in the loadout without any equipment? I mean, makes no sense. And i am not talking about what you can download model, i am talking fully ingame models. When you upload your item to the workshop and you can see it on the character, THAT character has no loincloth and bag instead:) I was confused and checked the loadout of my witch doctor unequipping everything, loincloth one without bag (as i remembered). So what the heck then? Also, i can make then a weapon for him, but that's not what i wanted to. Can't make only weapons, just because we only know for sure which one is the weapon slot:P

I have a bit of a problem, such as: I can't test my item which i want to place on witch doctor's belt, since in the game, the testing model has actually the BAG on his side, not the loincloth. Can it be optional or something? I can't see it and/or test the look of it, since the bag is EXACTLY at the place where I would like to place the item, so I'm not even able to check if colors are fitting in the ingame light, etc.. any help? Valve, something, someone? Can I check it in another program maybe?
