SOLVED: Camera.layerCullDistances how does this work ?

quote from the whats new in 2.6 page:

Camera.layerCullDistances lets you specify culling distances per layer.

i would really like to use this but how exactly does this work ?
where in the editor do i set the cull distance for a layer ?? i cant find it ?! and there seams to be no documentation for this feature yet either ?!

There’s some doc in the Scripting Reference.

alrighty so there is documentation:

i searched earlier and all i got was:

Scripting API Search Results
Your search for “culldistance” did not result in any matches. Please try again with a wider search

Oddly, searching for “culldistance” doesn’t return anything, but searching for “culldistances” does. I usually just search for the class name (in this case, “camera”) and look for it in there.
