Hi everyone! I’ve been, always, fascinated with this type of ink in water animation. So I decided to try and find a simple way to create this with Houdini. I love so much the result that I want to share with you how to make this ink in water. This will be a tutorial divided into two parts. On this first one, we are going to understand how we can create this smooth simulation and render it with redshift. On the next one, we are going to add custom velocity and mix colors. Hope you enjoy this Ink in Water tutorial!
