High dynamic radiance skydome panorama in *.exr and *.hdri format. Example scene in *.max file format included.
It is better to use as a texture on VrayLight in Dome mode (see example scene or Tutorial). You do not need to use additional lights (such as VraySun). This panorama were created in a special way to give correct lights and shadows. Just apply as bitmap in VrayLight texture slot, for example. 3d-preview (QuickTime needed): http://sky-hdri.net/images/icons/sky-HDRi-01_2010-09-06_15-00.mov
