@Rive eye rig setup using Claude and Rive MCP. While trying to get into the Rive CLI, I stumbled upon Rive MCP and thought I should at least try that before getting into the CLI. And MCP, together with Claude, sure is a powerful tool. This rig, while simple as it may look, is actually complex to set up. The face joystick controls where the character is looking at: front view, quarter view to the left, quarter view to the right, look up, look down. And at each of those angles, the shape of the eye changes due to a change in perspective. The eye joystick controls the eye direction, and depending on where it's looking, the eyelids would also slightly move. Pair all of that with a blink control, which again needs to control the same shape. And if you've rigged a character before, you would know how tedious it is to achieve something like that. This is for the singing girl project I posted a few months back, and I've been putting this off due to the complexity.

I know the structure of the rig; I know how to do it; it's just that it would take a very long time to set up. Come in, Claude + Rive MCP. I've prompted Claude with some context, and then gave instructions on how I would do it exactly, like create root bones to the exact position of the points, have the handles get their own root bones as well, then put those in a group, add transform constraints, create timelines, joysticks, etc. I've even asked it to create a script so I can execute it via the terminal (I can repeat the process without burning credits).
