I just downloaded Rekubot's DH-17 blaster pistol model and read Fragme's tut on fixing floating weapon icons and it worked....... partially.
Any help appreciated thanks.

well i think you should only add on the 1playerhud file found in data_xxx\Common\hud\PC the next line

MeshInfo("dh17")
{
Position(-0.264115, 0.358155, 0.013887, "Viewport")
Rotation(0.804269, 90.747269, 359.999695)
Scale(0.720000, 0.720000, 0.720000)
}
and this work fine think
