A selection of shots from Nazi Mega Weapons: Super Tanks.

Didn’t have much time to get these explosions delivered. Just one day of setup, and then 1/2 a day per explosion for more setup, sim and render.

The fume sim is driven by a particle flow system. I wanted to have a strong petrol based explosion type, with an initial large blast, followed by multiple secondary explosions as other sources of fuel are effected by the heat of the first explosion.

To achieve this I used multiple fume particle sources with different settings, and could adjust the amount of fuel and heat I was adding to the explosion with each blast.
