"It's a lot of fun. It's a plug-in for Houdini. You can source your fluids from VDBs, points, or particle networks. It runs on the GPU, so it's very fast. The downside is that I 'only' have 24 gigs of VRAM on my home computer, so there's a limit to how far I can push things.

It does all the things you'd expect a modern fluid solver to support. Variable viscosity, surface tension, and whitewater generation.

I wouldn't call myself a master of fluid sims or anything, but from what I can see, it's very cool and worth checking out. Theory Accelerated is the same people who make the Axiom pyro plug-in, so they have experience with making good production tools."

"For the dismemberment, I used Houdini's MPM solver. I think of it as 'particles on steroids'. You convert your geometry into points, and the points have different settings on them to mimic different materials. You could have the particles behave as if they're concrete, soil, snow, or rubber, there are a bunch of presets for different material behaviours.

I made some colliders inside his chest, and then had them rapidly fly out of him, which caused him to break apart.

I didn't quite get the look I was going for. I wanted the pieces to be rubbery and have jiggle on them. But if I made them too stiff, they wouldn't break apart at all, but if I made them not stiff at all, they behaved like grains and reduced him to a pile of sand/goo. I think I could fine-tune it more, but I just didn't want to spend a ton of time on it, and I eventually had something that was good enough.

For having the fluid emit, there's an MPM Debris Source, which spawns particles along the parts that break apart. I used that to spawn the fluid sim. That could have been fine-tuned as well. If the pieces hit the ground hard, they would break apart more, and a ton of fluid would be generated, probably too much."
