I try to record today many time the step by step but my poser crashed.. later i fixed my mashine so I am late sorry!! will post tomorrow in the morning everything..

and the radiance effect? just captured the light from the scene .. with a mirror ball but virtual , tomorrow more info about!
this is good but only to use in one scene and everytime you do new scene you have to make it again.. but well the effect is great and render much more faster as extra lights..
and the effect is good b/c the light come not from all direction as you see on the box only exactly from right and left.. you can use all colors what ever produce light or have a bright colors ...
