Vray IES light with profile spot (projector map?)

[fraggle]

Hello,

I' running short of idea to achieve profile spot with a photometric light (using IES file).
A profile spot, is a spot that shapes the light, round, square....

Such effect can be produce with regular photometric light using a projector map, but what about Vray IES light? Any idea welcome....
If I need to keep going with the regular photometric light, as I have 60 of them, what is the drawback compare with vray IES light?

Thanks

You can't create an IES file with a rectangular spot shape (the format simply has no way to describe this).
