We’ve been asked by Patrick how to pull off something like these beautiful paint smears in Houdini, so we got to work. Using basic FLIP techniques will get us quite far, we just have to find the right settings. (Haha. “just” finding the settings…)
In this tutorial Mo covers setting up a basic viscous FLIP sim using animated colliders to create the impression of acrylic or oil paint being smeared around with a brush.
