Sorry, I was planning to answer this thread, and got distracted. Really cool showcase of fluid effects.
I used to use fumeFx in Max for this stuff, and then I used a system in blender for a while, and now I'm using a few new plugins in UE5. I really enjoy working with fluid simulations, but the reason I don't do it more often is because it always takes forever to run the initial simulation. I remember waiting literally days for Max to build out a 10 second water event in 2010. The new stuff doesn't look as good, but it's a lot more fun to work with because it's literally hundreds of times faster.
Here's some of my old blender work.
I'm still working out a fluid pipeline in UE5, it's a lot more complicated this time because I have to simulate a lot of different real world scenarios, make them stable and repeatable, and have them run under 3 seconds a frame with simulation (non baked). I do run baked sims for certain things, like vortex portals.
Here's a quick video I made showing one of the new systems, for another thread a while back where someone was asking about reverse engineering things.
I'm glad to see someone else on here doing this stuff, great work man!
As far as the comment silence, high intelligence work has kind of an inverse response curve. You're on the right track. This kind of work pays off big over the long term, but doesn't get the quick kneejerk responses that you get from joke videos. I totally get the frustration you and buddy feel, spending weeks of hard work to do something amazing and then watching a video of a drunk guy dropping his iphone into an aquarium get 6 million views and 40k comments.
