Particles
Add some dynamic flare to your dice using particle systems. This is great for adding flame or spark effects. Currently, you can attach one particle system to your dice, and it will remain active while the dice is on screen.
Particle systems are built using a tool called Three Nebula. There is a desktop application available there that you can download to create your own effects. In the input box, you upload the save file produced by Three Nebula.
Our dice are about 1 "unit" wide. The sample particle system in the Three Nebula tool is much larger. Keep this in mind when building your own particle effects. Also keep in mind the view in the dice room is looking straight down the y-axis.
