We would like to do a small stream and have the possibility to animate it.

What should we use, realflow or phoenix ? and will corona be able to render it?

any advice would be much appreciated!

Peter

ps. I'm pretty sure I ask on various forums about water simulation every year.. seems like a technology that initially looks cool but then never sees much development

This could be another option

The video tuts are quite clear. I know development is still going on.

I think RealFlow is fastest, easiest to simulate fluid and still have enough power to do more complex tasks

Quickly answering the actual question:
and will corona be able to render it?
The Output of a complete simulation is a base fluid mesh, a particle cloud, animated displacement / normal texture and in super complex cases, wet map.
All these things corona can handle. Base fluid mesh is a simple volume, where you apply your water material.

If you want caustics you are a bit in a bind, as corona does not sample caustics well yet, it should not be necessary however, unless you are making a swimming pool. There is a workaround for that using a light to cast fake caustics.

Particles (splashes and foam) also work and are supported since 2013, not that you stumble across a forum post prior explaining particles aren't supported.
Wet maps will work in with corona, as it is a simple map, but you will cry your eyes out trying to get them imported and running.
Lastly, the realflow animated water displacement, which you can use as a normal map, have to be imported as the native 3dsMax bitmap, as Corona Bitmap does not support animated sequences yet.

Realflow is the expensive powerhouse, that can do it all, fast and incredibly well established.
Pheonix is integrated and requires no importing / exporting, but is not as feature rich and not as fast for big simulations.

I tried to use Lucid from Ephere on a recent project, but had to turn back midstream. Off course it might be me, but it seems quite a few on their forum are having issues with actually making it work.
