Using Sprite emitters for the fire.

Using this tutorial to get a basic understanding, I've made a sprite emitter to try and make the fire seem a bit more interesting, and as its the closest method to that of a games engine in maya.

I made these four particles to be used by the sprite emitter, making the backgrounds invisible and using .tiff files to include an alpha channel.

I also added some per particle expressions to make the image chosen random per particle, rather than being in a predictable pattern, and to add a rotation

In viewport 2 it still seems to ... break. but in the legacy viewport it looks like this. The colour gradient doesn't seem to be working and the incandescence isn't displaying properly in the renders.

 In the renders the colour isn't coming through and it looks a bit smokey.
