How I built a layer-based procedural explosion tool in Houdini — from velocity setup and Pyro simulation to VAT export and Six Point Lighting in Unity. A breakdown of the system architecture and the thinking behind it.

This Houdini tool was built to export animation and data from Houdini into Adobe After Effects in a clean and predictable way. When working with simulations, procedural animations, or technical setups, it’s often necessary to bring motion data into compositing tools. Doing this manually or through ad-hoc scripts quickly becomes error-prone and hard to maintain. This tool provides a simple and structured way to export data from Houdini and reconstruct it inside After Effects,

In this short video, I present a quick overview of the "Camp Fire" FX creation process using Vertex Animation techniques. I used Houdini 20.5 with Sparse Fire Simulation and upres techniques for Unreal Engine 5.4 with Lumen and Unity URP/HDRP 2022.3.4. Watch as I showcase key steps, including geometry preparation, loop animation, shader creation, and particle system building for sparks, hot air convection, and burnout sticks.   Like this post?
