Adding transparency to laser model.

[Rayce]

Alright, I'm trying to convert a blaster shot model someone made for Empire at War. (Not from the stock game) But I can't get the transparency to show up, so it looks like this (sorry about the loadscreen):

I tried hex-editing additive transparency using this tutorial, but to no effect. The model is just a bunch of planes and a texture.
