To complement our PBD Wire Setup, here is a tutorial on a topic I’ve personally been struggling a lot when I first tried wrapping my head around constraint networks. Similar to what we’ve been doing in PBDs, we’re gonna build a network of interconnecting wires – this time using Houdini’s wire solver.
Disclaimer: I wouldn’t have been able to pull this off without the help of Matt Estela’s CGWiki. Also nowadays we’d most likely use the grain solver (PBDs) to simulate something like the setup shown here. It is usually much quicker without giving much different results. Nevertheless should you run into a situation where you had to use constraint networks – here’s how they work.
