Explore advanced techniques for extending Unity's Animation Rigging package using C# in this 36-minute conference talk from Unite Copenhagen. Learn how to build custom rig constraints, add secondary motions to character rigs at runtime, and create authoring constraints to fine-tune animation assets within Unity. Follow along as Unity Animation Developer Sven Santema demonstrates practical examples, including a Jiggle Chain Constraint and a Wobbly Ninja implementation. Gain insights into the Animation Rigging overview, scripting custom constraints, and working with the Open Rigging Toolkit. Discover how to sync values to Animation Stream and inspect the playable Graph for more precise control over your animations.
