Particle Effect Research

Pressurized Steam 

I plan to make a particle effect that mimics the steam above for both my barrel (when the whistle blows to have steam come out of the whistle) and for my racing level for the pipes within the mines. 

This steam will blow out of a single point and grow larger as its life goes on.  For the emitters, I know I'll first need some sort of subUV set like the one down below:

I've been having a hard time finding a steam subUV thats free use that looks like the shape and effect I'm trying to make, so if I don't find one I'll have to make one myself.

I also plan to have another emitter make the cone of more dense steam in the middle, also having that effect be pure white and less transparent than the subUV emitter to give it a nice look of intense steam with some falloff.
And for the last emitter I want to have some denser water droplets that are too condensed to be steam and fall around the base of the effect. This gives the particle system the effect of steam pressure caused by heated water rather than just pressurized gas. I also want to add some sort of sound when the steam is in effect, as I want it to be triggered in my level by players driving through certain parts of the mines.

Heres my progress so far:

As I mentioned earlier, I've been having a hard time finding subUVs for the particle system so for now i've been working on base animations. Truthfully, I'm new to particles and it isn't coming very easy to me, but I do like the base effect of what I'm getting here just with the most basic material.  I'm still messing with the size by life module to make the sprites smaller when they are born but becoming larger over their life. Eventually, I think I will have to make my own subUVs, but I think its good practice and hopefully will help me get the effect I want.

Particles certainly are a learning experience...
