@rouncer81 ao is special case of hdr lightning (f.e. a really cloudy day around noon => unique distribution
of rays over the hemisphere).by using real hdri the hemisphere gets splitted into a number of light-energy hotspots (e.g. 64-1024) => higher ray coherency for a shading point. so today it is possible to achieve good
env lightning with 64-128 samples per shading point. here the most work has to be done within the visibility
really very impressive, but id like to see true environmental lighting in real time.

kernel == ao with scene radius.
