Important Nodes Learning from this example

This shelf tool sets up a sparse pyro simulation of a large scale explosion and shockwave. These are broken up into two different simulations to give the artist more control. The shockwave is advected by the velocity field from the explosion. It provides a good example of how to use multiple Pyro Burst Source nodes to create good looking explosions and shockwaves as opposed to doing all the sourcing in one node.

Important Nodes ¶

pyroburstsource

Sourcing for the main explosion is split into three sections, which all create specific shapes in the simulation. These sources are all generated by various Pyro Burst Source nodes.

The shockwave sourcing also uses this same approach with two separate Pyro Burst Source nodes.

Learning from this example ¶

To...	Do this
Change the size of the explosion and shockwave	Adjust the Outward Expansion and Directional Expansion parameters in the Pyro Burst Source nodes.
Change the shape of the explosion and shockwave	Adjust the Shape Offset or Offset parameters in any of the Pyro Burst Source nodes to easily modify the shape of the explosion or shockwave.
Adjust shockwave advection from the explosion	Dive inside the pyrosolver_shockwave1 node and adjust the Source Scale parameter for vel in the Sourcing tab of the explosion_vel1 node.
