ACR Flame/fire mapmodel help

[-{ET}-xdEpicZombie]

I know that in ACR you can make movable mapmodels with gif image textures that change.My question is that can I make half transparent mapmodels?Then I could create a more realistic fire model!
By "more realistic model" I refer to the torch model for AC that was a big step but still not good enough!(I cant find the model but yeah...)

I don't think you can have any transparency...

I think you can, trees work just like this.

I thought trees used complex polygons.

[rXn]

That's how they do it.
