How to create rectangular IES light in Vray?

is there a possibility to create any other form of IES light other then cone in Vray?
I need to create LED rectangular form plate using IES file.

Some thoughts:

  • the IES light cone is only a Rhino widget and doesn’t determinate the light distribution, since the IES data control it
  • the IES light source is invisble for the camera, but you can place a textured emitter like you need it, for example rectangular
  • you can choose a basic shape for the IES light source so that the shadow get the right blur amount (point, circle, sphere)

Thanks, I’ll try it
