My mod has a set of tools and armour as the highest tier that should cycle through every hue value and overlay the colour onto the item texture. However, with my sword renderer, I end up with http://puu.sh/c1Q0q/42bf7e4465.png, http://puu.sh/c1QlN/fcdcb7dd54.png, http://puu.sh/c1Qwu/576c1ca1fa.png, http://puu.sh/c1QDU/1db230b12d.png and http://puu.sh/c1QOp/9e1b62746a.png - the scaling is off (I messed around with that for a couple of hours), the colour doesn't blend properly except in the inventory (where it has an odd background), the item entity doesn't rotate to face the player (or spin at all with Fancy Graphics on) and the item is 2D.

Can anyone please tell me what I'm doing wrong and how to fix it?
