  Master Houdini Vellum Disintegration through simple and flexible techniques. Use particles to add details and instance additional geometry for a layered result.  There are many ways to create disintegration effects in Houdini, with most setups relying on complex logic and extensive VEX coding.  In this course, we’ll take a straightforward approach that balances simplicity with flexibility and artistic control.  Alongside the core effect, we’ll add particles and debris, set up a lighting environment in Solaris, and finish by compositing everything in Nuke.
