A little off topic… that is one of the most beautiful sites I’ve visited! Yeah, I’m a sucker for blue!
From what I’ve seen though, RealFlow pales into insignificance compared to ScanLine FlowLine:

Couldn’t comment on RF4 though, their Flash feature video gave away nothing.
Then again, you can actually try/buy/use realflow. 
Where’s scanline in each of those steps?
Realflow is capable of some amazing stuff if you push it enough. Wait until Poseidon comes out and you will see, it can look pretty much as good as anything out there.
But, regarding Flowline, repeat after me:
IT’S. NOT. A. COMMERCIAL. PRODUCT.
It’s like comparing off-the-shelf software to LPics, or Storm, or MudBox, or Gossamer. If you don’t know what those products are, it’s because they’re proprietary software, unique to a single house’s pipeline. And they don’t have as much of a PR department. 
Excuse my ignorance…
What’s Poseidon? Once again sorry if it is so obvious for some people… 
The Flowline website and all the stuff being advertised does give the suggestion that it would be at some time available to by or on a per licence useage.
Thats how i read it.
Yes, and when/if it becomes commercially available, we can all make judgement calls. It may only be able to do a very finite number of things. It may be very slow. It may be a system hog. It may be extremely difficult to use. Who knows if it even has a GUI? My point is, the comparisons aren’t fair. It’s like when everyone was going on about the Killzone demos that turned out to be pre-rendered – we simply don’t know anything about how those shots were made, yet. So l reserve all judgement until such time as I know what I’m dealing with. Right now, Realflow is the only real choice on the market, and it’s a pretty good one.
Hi Bonedaddy,
Have you use realflow intensively??? How is it handling millions of particles in the scene?
We have been using it for various projects but the most I pushed was 500.000 particles, cached 2 or 3 different sims and make a big mesh out of them… We do not have fancy super computer, so it’s a bit slow and crashed several times. I managed to get all I need without trouble (fingercrossed) but I kept wondering how is it performing for big water scene…
Thanks
I do a lot of rendering work for super yachts and I would love to be able to create much more realistic boat wakes than you can currently with Realwave. Once again it looks like this part of the software has had little or no attention. 
Yeah, NextLimit is pretty much known for using good advertising to over hype their products and distract consumers with pretty graphic design. I woudln’t expect them to meet their release date either, or have a bug free program when they do.
The linux version is a lot more stable.
I’m happy to see there is also a 64 bit version. That means a lot more of particles as well.
I have seen guys pushing RF sims with several million particles, with some stuff to make it restart if it fails. It’s a bear to work with, and is missing some pretty key functionality (I -still- cannot figure out how to hack an “inherit emitter’s velocity” w/it), but it’s what we got, for right now. My personal experience is pretty minimal, but I have seen some of my past co-workers push it to do some pretty impressive stuff, but it took many hours, and many headaches.
The thing about realflow, is that it gets more stable everytime you use it.
This is because its very unforgiving to crazy values and settings. So as a noob you constantly crash it as you use rediculous settings, the more you get to know the values and their results the program settles down a lot.
Regarding RF4 - I have one comment to make: “Evolution, not revolution”
Its like another porsche 911 released on the market. A few updates here and there but nothing partiularly exciting.
NextLimit have a forum FULL of feature requests for the next versions of realflow, and hardly any of them seem to have been announced/implemented yet. Its a pretty poor show so far from what i can see.
Having said that, the software isn’t released yet, and i really dont expect it to be out this summer. Unless it’s actually finished and they are just putting a date that they will definately meet just to shock us. 
Oh and 2 major requests that dont seem to be present:
- Presets
- Enhanced simulation/relaxed fluid states
