Tips and Tricks for Simulating Thin Ink With Houdini

Simon Trümpler covers what to look out for when simulating thin ink effects in Houdini.

With Side FX Houdini, advecting particles by the velocity in a smoke simulation is great for getting an ink-in-water effect. But there are some things to watch out for when creating this thin ink cloud effect in simulation. 

This new tutorial by Simon Trümpler explains some of the issues he encountered while making a thin ink cloud effect. “I also explain my issues with the rendering and explain some “gotchas” you can avoid while re-creating the VFX.” and that includes updating velocity instead of force and the importance of providing enough points in your source.
