CG Generalist, Tim van Helsdingen, shows how you can create dynamics with low resolution meshes, and then apply high resolution ones for the Houdini simulation. Working with lower resolution geometry can be more efficient in a Houdini simulation.
Admittedly, Tim notes that swapping out low for high geometry is a simple thing in Houdini. To his surprise there was little information floating around describing the process, so he created this tutorial to help people along.
If you are looking to up your skills, on destruction and Houdini Simulation… You might want to learn from the Senior Rigid Body FX TD for Industrial Light and Magic, Steven Knipping. Steven’s credits include the VFX-heavy films as Star Wars: The Force Awakens, Avengers: Age of Ultron, Tomorrowland. The three part Applied Houdini Dynamics series is packed with great info. You can currently pick up the Applied Houdini Dynamics Bundle for a discounted $69.99 through CGCircuit.
