We’ve had so many requests from people wanting to try the beta now, that we’ve added a buy button to the UP page. If you have’t already done so, please try to demo to make sure that UP works on your machine. There will be no refunds once we’ve given you a license code.

Please make sure to watch the new Surfacing video

The new Particle body type work has just begun and is probably not stable.

The baked meshes are saved as a LWO sequence in a folder called “Up_fluid_meshes” in your Content/objects folder
