In this tutorial Moeen will be going through how to create a Doctor Strange-style portal effect in Houdini. It's VEX heavy and can be a lot to take in but we're trying to make it easier for everyone by going through it over at our blog post. We'll try to keep our next tutorial a little less VEX intense for anybody who is trying to avoid VEX like the plague. But, for now, we'll get you thinking with portals.
The music used in the intro: Charles the First (ft.Clozee) - The Mist
