Getting started with fluids and Vray.

[LL_Will_J]

Hi,

I was wondering if anyone has much experience with rendering fluids with Vray. We have a project coming up with quiet a few shots that will need some fluid stuff. Currently we are looking at using either FumeFX or Maya fluids.

We have tested the workflow of getting FumeFX exported to field3D and importing that into a a VrayVolumeGrid. This seems to work well.

Also we seem to get some reasonable render times adding the VrayExtraAttribs fluid shading quality to the Maya fluid.

But my main questions are about then using Vray to shade those fluids. I have read about the PhoenixFD shaders now being bundled with Vray 3 - but I am not sure how this works when using the Maya fluid container properties.

Also are the shading parameters in the VrayVolumeGrid the same as the shading properties of a PhoenixFD shader?

It seems like you have more options in the VrayVolumeGrid than the you do when applying the Fluid Shading Quality to a maya fluid. This makes me think I should be exporting the Maya fluids to an .openvdb or a field3D (naturally Maya doesnt support either straight out of the box!).

If anyone has any advice on how to get started with this - it would be greatly appreciated!

I don't have any advice , and going through the same , but the render time seems really slow for me, I love the light interaction and all, but the render time are slow ( they 're already slow with mental ray , just complaining comparing to what I can do on houdini's mantra. )

What about bifrost? Have you looked into that at all?
