Hey
you can fix that easily with
just install it, open the act you want to edit, and edit every position of the item (front, sides, back, when char is sitting, on foot, walking)
it's very intuitive and easy to use!
If you wan't to disable it all just add this --[[ and --]] in the beginning and end of it like this...
After that save it if your done with it then add it into your custom grf via patch or add it directly into your grf using GRF Editor.
