I used 2 particle effects.
- was for the internal white color you would see in an explosion
- was for the surrounding orange, red, and yellow.
I used trailing on both to create a very densely packed visualization and used about 10000 particles for the internal white particle effect and about 30000 for the external surrounding effect. I then scaled it to 5x by 5y by 5z for both of the particle effects objects and then added them to a new empty game object called explosion.
