When 3ds Max 8 bipeds decide to rebel 🕺

Imagine this scene: you're religiously following the Crowd Simulation tutorials in 3ds Max 8, using the Biped Crowd. Everything is going smoothly when working with the swimming animation, where the bipeds obediently follow the delegates like ducklings behind their mother. But then... you decide to switch to a running animation. Fatal error! 😱

Suddenly, your characters abandon all logic and start spinning in circles like drunks leaving a tavern. The delegate, which should lead the group, now follows the biped like an obsessed fan. What the hell is going on here?

P.S. If your bipeds insist on dancing, at least put some music on. You might discover the next TikTok viral. 😂
