I was downloading some mods from ac.amir's blog, and I happen to find a post that captured my attention.
Hitman Absolution (http://gtaiv-skins.b...absolution.html)
But the problem there was the pants (lowr_000_u.wdr) were floating a few inches from the ground.
So I searched for alternative pants models from his blog again and found one that WOULD have fit perfectly:
Michael de Santa's pants from (http://gtaiv-skins.b...characters.html)
The problem was it was slightly positioned forward compared to Hitman Absolution's pants and uppr models.
Now back to the question - How can I move the pants forward?
