Using control rig to create fully procedural walk animations, for a spider, but discussing the same concepts/nodes that can apply to bipedal characters, or any other form of procedural animation.
100% made within control rig, other than hooking up the animBP, so it’s efficient performance-wise. The techniques/methods aren’t necessarily going to be ideal, and it’s more aimed to be an overview/intro to making procedural animations, rather than literally what you’d do in a production setting.
The spider character download is also linked in the videos description if you want to have something to use to test with or follow along, but I’d recommend watching the tutorial in full to understand the concepts / nodes / process, rather than trying to directly mimic the steps.
