Learn how to create impressive disintegration effects using the Houdini Pyro Source Spread operation to create a gradually spreading simulation. Whether new to Houdini or a seasoned veteran, this workshop is designed for all user levels. The final file is included as a learning resource with this workshop, so you can open it up to study and make your own edits and alterations.
In this workshop, you will learn simple VEX coding and how to use the Houdini SOP Solver. With this, you will learn how to maintain control in and out of the DOP Network and discover how to create additional particles and volumes on top of a cloth simulation created by the Vellum Solver. Choi Gil Nam also instructs how to use Houdini COPs and Nuke for simple compositing.
You will also be able to apply the concept to Bullet and Flip Solvers. The goal is to provide you with a quick and efficient workflow that you can apply to your projects with the ability to present your work effectively.
Project files include the .hiplc disintegration files.
7 Lessons
In this workshop, Mads Drøschler provides the foundational workflow for preparing an animated character in Houdini for visual effects work, specifically a disintegration effect. By leveraging free resources and following proper procedures for importing and scaling, Mads demonstrates how artists can efficiently set up character-based projects.
Duration: 2m 14s
In this lesson, Mads dives into a workflow for creating sophisticated destruction effects on animated characters. Mads explains how to control exactly when the simulation starts by using custom settings that update as the animation plays. This technique allows for precise, art-directable disintegration effects that stay perfectly attached to the character's movement until the moment they are meant to break apart.
Duration: 21m 5s
This lesson provides three progressive techniques for creating realistic spreading effects, ranging from simple color transfers to more advanced automated systems. Mads shows how to achieve natural results by experimenting with settings like cooling rates and search distances to control how fast the effect moves across a surface. These methods can be applied to various scenarios, including cloth and particle simulations.
Duration: 15m 50s
Mads presents a comprehensive workflow for creating fire simulations by combining smoke and particle systems. By carefully controlling how the fire burns and layering forces such as wind and turbulence, Mads highlights how to create realistic behavior. By letting the particles respond to the fire's motion, the final result shows cohesive interaction, demonstrating that a proper simulation hierarchy is essential for believable effects.
Duration: 27m 2s
This lesson provides a complete pipeline for creating and rendering dynamic spark effects. Mads explains how a modular approach allows artists to save individual elements separately and combine them flexibly during the final stages. The key to achieving professional results lies in proper blur settings, making the colors react to heat, and using the sparks themselves as light sources to create a physically believable look.
Duration: 25m 16s
This lesson shows how to polish shots in industry-standard software. Mads demonstrates how separating different parts of the image allows for maximum control and shows how similar visual results can be achieved using different tools. Understanding these different workflows is valuable for professional studio environments.
Duration: 12m
The critical takeaway in this final lesson of Mads' workshop is understanding how specific movement settings control simulation behavior, enabling precise timing for when objects break apart. Mads highlights that layering multiple techniques enables artists to achieve complex, realistic destruction suitable for high-end production.
