How does it compare to flip or mpm ? Is the result of the paradigm solver statisfying for you ? Just curious cause I haven't tried it yet.

Better faster easier. Do read the short docs though or download example scenes.
The default settings won't do anything. For instance, in the solver you need to go to advanced settings and check trial mode for the demo mode. Also the default shape node needs to emit particles (in source) and be connected to the shapes (not particles) input for a water sim.2

Feels good to me with how fast that water is flowing and all the rocks breaking the surface, the dissipation of it looks solid as well.
How was the setup time compared with mpm or flip?

It doesn’t even compare tbh. Paradigm does the whitewater solve within the same sim, so its honestly a matter of just tweaking a few parameters. Pretty plug and play.

I really love how the pig head spins so realistically. It shows how powerful Houdini is. 10/10

Can I ask which node you choose for the water geo?
And did you use the Karma whitewater?
