Done way before any connectors/exporters from Naiad to Vray were released.
3dsmax with Vray renderer.
Mesh is about 30 000 000 of polygons in each frame.
Rendered with Global Illumination and fully raytraced reflections/refractions.
Took about 12 minutes to compute irradiance map (gi prepass) and 14 minutes to render a 1280x720 frame on my 12 core pc with 12Gb of RAM.
All standard vray lights and shaders.
