Foam Sprayers
Introduction
This was my attempt trying to recreate the foam techniques from the amazing PROTECT project from XK Studio. Shown below is one of the frames from their project that I used as reference.
For more insight in to their process and development, take a look at their video here: XK Studio BTS
Below are some of my results while testing and iterating on simulation settings.
