by I’ve had a number of people ask me about this effect, and it’s something people seem to like a lot, so I’ve decided to put together a tutorial and an annotated hip breaking down how it works. The tutorial walks through the ‘standard’ version of the effect, from scratch, then I briefly discuss a few variations – which are also included in the hip!
Beginner/Intermediate level. Assumes basic familiarity with Houdini and VEX, but otherwise nothing wildly complicated!
I hope you find it useful and/or interesting, and please comment or drop me a line if you’ve got any questions, ideas for improvements, or any tutorial requests!
