Realistic Balloon Simulation with Blender

Danbo with his Balloons.

The biggest response from our Danbo on the Coffee Table Camera Tracking Article was, 'How did you make that balloon float around like that?'. So we pulled together a 15min video tutorial.

It's a really simple process, add a cloth modifier with negative gravity. Tweak some cloth settings and bake the cloth simulation. We then go on to explain how to have the balloon held by a string and for that string to be waved around by a character.

We'd like to post some videos or stills here if any of you decide to have a go yourself. You can email us or find us on Twitter or Facebook.
