Culling masks in deffered lighting

Hi,

According to unity’s page about deferred rendering :

http://unity3d.com/support/documentation/Components/RenderTech-DeferredLighting.html

It says : “Disadvantages : … limited support light Culling Masks”.

I would like to know more about this limitation. I’m guessing that culling mask doesn’t get stored in the G-buffer, so dynamic lights can’t know if a pixel is supposed to be lit by them or not. Is this the case? If so, does the “limited support” mean that baked lightmaps are still able to mask-out objects using culling masks?

Thanks!

I’m wondering about this very issue. It seems that Unity completely ignores any light layers I attempt to implement. This makes preventing issues like this pretty much impossible:

I look forward to a post from the Unity team regarding how to deal with light bleed issues such as this if culling masks wont even solve it.
