Explore the entire process of creating electricity and lightning visual effects using Houdini. Using a generalist approach, each chapter focuses on the essential stages of a complete, professional VFX workflow using Maya and Nuke in addition to Houdini. Artists will learn, step by step, how to integrate a custom character animation into a robust Houdini effects setup, covering everything from project organization to final-frame rendering.


Beginning with asset prep and animation, Josh first covers how to prepare character models and animation for procedural import into Houdini. The first chapters also offer simple workarounds for rigging in Maya to provide more agency and flexibility to independent artist creators.


Transitioning into Houdini, Josh then demonstrates how to set up materials and shaders in Mantra, Houdini's native render engine, to develop the scene further. From there, the workshop focuses primarily on generating lightning effects. After analyzing in-depth the fundamental concepts and approaches to creating electricity, Josh slowly explores more advanced techniques, instructing on how to make both secondary and tertiary elements, in order to add detail and complexity to a scene. He also discusses how to utilize particle and pyro simulations in order to generate dynamic electricity movement. After finalizing and finessing all the lightning elements, the final chapters guide artists in how to convert meshes into renderable light geometry, how to create custom AOVs in Mantra, and then how to use those render passes to create a professional composition in Nuke.


Josh’s Anim.character.001.abc file is included as a downloadable project file with this workshop. The Mike Freeman rig by CG Truong and the Spartan Hoplite model by Ryan Reos are also featured in Josh’s workflow.

  • I met Josh during my time as FX Supervisor at Luma. He proved to be a really driven artist, capable of creating some visually stunning effects and carrying it all off with a great attitude. He made it easy to discuss strategy with and was really fun to work with. I've enjoyed watching him continue to push himself as an artist over the years. Especially when left alone to his own creative instincts like we see in his personal projects.
