Hi…
Just looking at the docs - how is the effect at the beginning of the video achieved?

http://www.sidefx.com/docs/houdini/shelf/vellumballoon.html#working-with-vellum-balloon [www.sidefx.com]

I can find no way of actually inflating/deflating Vellum.

Maybe we can get the hip file used?

Cheers!
Nick

You can use vellumconstraintpropertyDOP to animate the Compression Stiffness.

Basically you have to add an additional force on each vertex that points in the direction of its normal. That's all inflation really is. there's a good thread on it somewhere, I'll see if I can find it
