Rohan Dalvi covers the new attribute nodes in Houdini 18.5 and how they affect smoke sims.

Houdini 18.5 completely re-wrote the Attribute Noise SOP to work with all levels, be more convenient, and have a bit more power behind it. 

The Attribute Noise SOP provides a simple interface for quickly adding coherent noise to float and vector attributes without creating VOP networks or writing VEX code. Those noise changes also mean that you need to work a bit differently.

This new tutorial by Rohan Dalvi shows how you can work with Attribute Noise and add noise to the density, temperature, and other attributes from a pyro simulation.
