We are now carrying FluidRay RT Real Time Renderer at Mirye Software. If you haven't checked it out, there is an integration plugin available that works with Shade 14 (and next version of Shade 3D). The plugin is currently only available for Windows, but a Mac version is in development.
We've set up a separate forum for this product - if you have specific comments about FluidRay, please make them there, esp feedback about the integration with Shade 3D.
There is a free, 15 Day demo - check it out :-)
