I think it is time for a new Vray Light type. I have been trying for a while now to get other options to work and I always end up giving up something critical.
What I need Is a Vray Spotlight. It would be similar to a standard Photometric Spotlight but would play better with Vray, Light Mix add some enhancements. The ability to add a map (or two!), adjust the focus and Beam Shaping. Chromatic aberrations would be cool. The ability to replicate a Fresnel lens
Directionality as a 0 to 1 parameter is just silly. Give me real world units and accurate photometrics.
So many uses for something like this, especially for film and theater folks.
