“So in this case, when Seyka reaches around and starts going through the hair right there, we actually animate a capsule like a movable collider,” he says. “We actually animate it at the same speed and the same position as the arm is actually going, which responds to the hair and it actually looks like her arm is moving away the hair to make room for the arm to hug around. I think that's as simple as I can put it, hopefully.”
This change was made possible thanks to Jolt Physics, an open source physics engine that Guerrilla switched to for Forbidden West. Among its many other advantages, it allows there to be more objects with actual physics in a given scene, such as allowing for Aloy’s numerous hair strands
