I want to start on a project that involves some "waterbending" like effects, and I was wondering whats a good way to make water? I know about realflow, but that's a bit of a wallet killer.

If you're trying to do waterbending type stuff you could probably get away with morphing an object through a bone chain. You could also run a displacement through the object to make it look watery and organic.

The nickdigital solution and a nice refraction (1.5) could work if the mesh is a solid body (not splashing)

Care to elaborate on this? I'm also trying to do something fluid related. Some drops following a path and forming a logo.
Thanks in advance and sorry for slightly thread hijacking.

Crude but you'll get the idea.

Here's what I'm getting on VPR: (Kitchen HDR probe, Transparency 100% refraction 1.2, Diffuse, Spec, and reflections all at 33%)

I guess this would work with bubbles and whatnot, and it's an extremely good method for that, but what about splashing and whatnot? couldn't we use HVs? maybe HVdeform? The surface mode for HV's has a blending function.

You could use HVs but they're not a true fluid simulator. You can get decent results but they have their limitations.

You can also combine the 2. You can make your water geometry an emitter with short-lived particles. Then it can leave a trail of HVs.

Great Idea- I'll try it.

You mean you can't see the HVs at all? Make sure that the HVs are turned on (object checked in the HV panel).

Very quick test, the same scene with the same settings you posted (just with a different probe and a bit of turbulence). If you give the surface HVs the same texture settings, they look almost like the geometry.
This is just 2 HV emitters following closely with pretty much all default settings and also using the same texture settings you posted. One has 175mm particles with 500% stretch, birthing at 240 and the other has 95mm particles with 400% stretch, birthing at 440, and with a 4m/s explosion. Quick deaths so they don't get too dense.

Still renders in less than 5 seconds on an old computer.

@nickdigital

Thank you!!! That looks very interesting.

OnlineRender gave us a link for using blender's fluids in Lightwave, right? wouldn't that be the best option? (as long as I don't have to touch blender for more than five minutes)

blender & LW .

maybe not the best option but the cheapest . . . HV's are SLOW

OK. I'm going to upgrade to lion now. The people who made blender fluids said something about it not being compatible with LW10? so Is LW 9.6 compatible with lion?
