Steam Particle

Here's my final Steam particle shown in the video above. These Steam particles I made for my level in the mining caves where they burst from the pipes and obscure the players view. Particles for me are a tad difficult, but I think I accomplished some pretty cool things for this project.  First off, I created my own subUVs:

 

This was the first time I had ever attempted to draw anything for something like this, and I was fairly pleased with the results. Although, I did take me a few tries with the second smaller set to get a result I liked - the first attempt for example had shapes that were too recognizable on an individual level, so it was really easy to see when certain particles repeated.  Here's the full final particle system: 

I ended up using both sets of subUVs along with a GPU emitter for the small water droplets that fall from the source of the steam. With the water droplets, I had to exaggerate their size because of how dark the mine caves are in my level where they are placed along with how fast the player is going, its hard to pick up on the smaller water droplets. 

On both subUVs I also put a damping node in their material so that when the cars pass through the smoke or when it hits the ground it fades slightly at the edges so the transition isn't so harsh.

I also made a very simple steam for my train using the same subUVs in a slightly different way!
