how do i make a halo assault rifle number plate in gmax? can someone help me wit this please?

I'm assuming you mean an ammo counter? You make a plane (one for each digit, so if you have a clip of 0-9 bullets, one plane, 10-99 you need two, 100-999 you need 3...) where you want the counter, and apply a bitmap to it for the assault rifle counter. It actually can be any bitmap, although I'd recommend getting the actual one (open in tool, printscreen, cut it out) so it's UVWed correctly in the end, and applying the assault rifle's shader to it in the end. Then there's some tag work to be done to get it to display the correct number, copy the assault rifle for that.

ok thx
