How to Stop RBD Sims Moving Forever in Houdini

Inside the Mind shows how to stop RBD sims from continually moving all the time in Houdini.

Rigid body simulations are fun, but one common thing is having the object continually moving even when it should stop. You may have had tiny fragments jitter constantly or some shapes with continuous movement.

Here, Inside the Mind (Stormz) shows how to prevent objects from moving forever.

Stormz shows how to prevent continuous movement in bullet simulations by reducing the velocity and angular velocity over time.

In the last little while, we’ve seen Inside the Mind (Stormz) cover a lot about rigid body dynamics solvers and constraints, which is a continuation of that. Also, visit this tutorial from Rohan Dalvi shows how you can help guide rigid body simulations in Side FX Houdini using the Guide Geometry Node if you want even more control over RBD sims.
