Houdini 21.0 Shelf tools

Staggered Ground Shockwaves shelf tool

Creates a medium scale multi-shockwave simulation with staggered start frames.

On this page

This shelf tool sets up a sparse pyro simulation of multiple medium scale shockwaves that expand out from points scattered around world origin. These shockwaves have staggered start frames, creating an interesting effect.

Important Nodes

pyroburst_shockwaves1

The pyroburst_shockwaves1 creates the source points for the shockwave simulation.

pressure_disturbs1

The pressure_disturbs1 inside the pyrosolver1 node is responsible for breaking up bulbous shapes. You can use Strength parameter on this node to create stronger breakups. To change where the breakup happens, use the Control Range parameter on the Control tab.

Learning from this example

To...Do this

Create more shockwaves

Increase the Force Total Count parameter on scatter1 node to spread the shockwaves further apart.

Change shockwave timing

Adjust the Min Value and Max Value parameters on the attribnoise1 node to control the timing of each shockwave.
