I get at least an additional 2 mins per ies light in a lc calc

Yes indeed they use alot more time pr light.

I have experimented with Advanced Raytraced Shadows with 'Simple' AA. And it often fly's compared to VRayshadows.
But when the scenes get very large and/or have many IES lights, VRayshadows seems faster again. Not sure why - but this has been an issue since the latest official VRay build.

Also if you render without Store Direct Light - it eats your time.

I have had to switch to normal spots again with projector maps

Some development/optimizations is something they should look more into. I think many readers in here (or more passive VRay users) also needs some speed gain here.

I often use more than 250+ lights and I think im not the only one

Vlado - any comments on this? Thx.

This has been an issue for a while, I had hoped it would have been resolved by now.

Anyhoo maybe a patch instead of SP1 eh

This has been an issue for a while, I had hoped it would have been resolved by now.

It cannot be resolved in any other way than us writing a new IES light plugin; even if/when we do this, the issues with the standard 3ds Max photometric lights will remain.

writing a new IES light plugin

that would be gr8!

[GALACTUS]

Cool... maybe a section under VRaylight parameter to load and adjust IES data or maybe a new VRay light type, might be easier to do than fiddling with 3dsmax photometric lights as they currently stand.

+1 Vray Ies

[m_hinks]

yes please, ies would be sweet. Although I must say, im using a few in a scene now and they are rendering nice and quick!

[rmejia]

VRay IES would be really nice, right now I have a scene which I have to change all the lights to standard lights because the IES is like 100x slower. IES lights with the render speed of VRay lights would be amazing.
