Ies

Is there any issues with IES lights in the latest MAX or V-Ray? Several jobs and I haven't been able to get them to work.

I find them pretty much useless unless you actually add an IES file into them

I was using an IES file. I ended up using RT, encreasing the brightness until I could see it, and ran with it. The intensity is so high I would have never had gueeses it had to be that bright.

If you have problems with VRayIES lights, please share the files or even better - the whole setups so we can check them. Also, please note that there are many not so decent IES profiles circulating the internet.

Is there a reliable source with IES files that work fine with Vray? I often have the problem that I need to manually edit the values of the IES in notepad because it has negative or flipped values.
