How to Render Image Based Lighting

Hi Everybody..


 I am working on a realtime project in which i need to use Image based 
lighting in my scene.. I want to lightup my CG world and create LIGHT PROBE
image 
map from the scene and use it in my realtime project.. 

Is there anyway direct option to render LIGHT PROBE image form a complexly 
lighten CG world. or else it would be great if some of you could help me to 
get the LIGHT PROBE image map from my scene..

you can make the light probe solution via skylights and either light tracer 
or mental ray with final gather.  then for realtime you'd bake the solution 
down to textures with the render to texture feature as a snapshot of the 
solution kinda like a frozen moment in time.
