Hi dear fellows

Trying to reproduce the video with multiple interraction called "H19 | Vellum | Unified Soover | 1" at https://www.sidefx.com/products/whats-new-19/vellum/ [www.sidefx.com] but I cooldn't find how to have the revolving wheel fixed by his axis and reacting to the fluid collision.

Any help from the team at the top of the clouds ?


Thanks

Yes I’d also like to know the correct way to approach this.
See the attached file.. I've done it using a shapematch constraint on the wheel to fake an RBD, then pinned a centre point, and in this example use grains to cause the wheel to spin about the pinned constraint. BUT it really doesn’t feel like the way they did it in the launch video and I can’t then figure out how to stop the wheel going off axis (perhaps a collision object either side might?)

If anyone can offer any insight, then I’m sure the original poster and I would be grateful.

I'm also interested on how to do it, no one can help us ?
