One common issue with continuous emissions is velocity buildup.

Over time, simulations can become overly aggressive and harder to art direct. In this tutorial, I break down a simple but powerful technique to counter that behavior.

You’ll learn how to:

- Prevent unwanted velocity accumulation in pyro sims
- Use Gas Damp as a counter-force to gradually remove excess motion
- Maintain cleaner, more controlled fire and smoke behavior while preserving your source density

This is a quick, practical tip that can make a big difference in how predictable and directable your simulations feel.
