I just tried to render some maya fluids, and it was rendering nice with vray. But when I try to render using the “maya vray deep plugin”, the fluid renders black in the .vrst file. So I guess that fluids are not yet supported by the deep plugin?
For the fluids to appear in the deep raster file, a special rendering mode for fluids is required where the fluid is represented as actual geometry to the renderer. Currently we have this available as part of the Phoenix FD shaders; we need to expose the option for Maya fluids when Phoenix FD is installed. I will see if we can add this easily to the nightly builds. You’d still need the beta of PhoenixFD though, even if you are only interested in the Maya fluids.
