Scaling VRAY IES?

[Macker]

Hey guys,

I've been working on a couple of interiors and noticed my IES lights creating some unusual reflections (the disc of the IES was being picked up in the reflection for whatever reason) so I scaled them all down a little, just enough to fit inside the light fitting and in doing so the power output appears to have shot up in the render. I have my units set to lumens, so I'm assuming it is some way these are calculated?

Any help much appreciated.

Nobody else have a change in intensity when scaling an IES?

I rarely use ies, but I would strongly advice against scaling a light or a camera with the scale tool (if i understood correctly) cheers

scaling camera with scale tool cause dof and some other effects to render completely wrong. I thing you dont want scaling ies too.

I didnt even know it was possible to scale an IES light or any light for that matter.

just override the shape of ies. and turn on "use shape for: illumination and shadows" for proper lighting.
