Substeps in Houdini - what are they? how to use them right?

In this video, we’re looking into substeps. It’s one of those things that is unnecessary unless something stops working. But when it does stop working, it’s essential to know how to use them right! The truth is, increasing the substeps is usually not the best way to go, so make sure you really understand how they work.
This knowledge will be especially helpful for simulations, but you’ll also find here some helpful tips for Houdini workflows in general.
We’ll discuss:
- Substeps and subframes
- VEX functions - $F, $FF, $T
- timeblend SOP
- Lighter POP simulations with fake substeps
- Troubleshooting RBD simulations
- Dealing with fast-moving colliders
Thanks for watching and I hope you found it useful! :D

Thank you for this material. It was helpful to me. I have already applied the information contained in it in practice. THX :)

Underrated content! Been using Houdini for 1 year and definitely understand more about what's being used after this video. Thank you.
Should start a pattern for more advanced topics etc.

Thank you ^^
