How To convert Photometric Light into Vray IES light

[fraggle]

Hello,
I do have a scene with plenty of photometric light but None of them are visible and they can't be turn visible unless I change from point to a sphere (in Shape/Area shadow).
Doing so extend the render time dramatically, so I'm looking for a solution to convert such target light with photometric web distribution into a Vray IES light.

By the way All light are an Assembly (fixture + light).

Thanks

Well, the VRayIES lights are not visible either, so how will this solve the problem?

Best regards,

right,
I add a vraylightmaterial on the mesh.
But I wonder why IES light that are acurate lighting point, can't be visible?

"Point" is the key The IES profiles describe the light distribution as though it comes from a single point of space. The fact that you can specify a shape for them in many renderers is a convenient cheat. With that said, we do plan to do some more work on this.

I notice that IES light takes a lot longer than Vray Light. Really a lot!

Is it normal or it's a bug on 2.2?
Thanks
