I found this one of the best looking render setups, and it seems as if no one is using it anymore... The reason why i ask is because i have went through the tutorial over and over and i still can't seem to get it right.. I need good Hdri rendering, and lightgen seems to be able to produce good results.. anyone want to give me a quick overview would be helpful,.

I find that using the Spinning light trick with LightGen derived lighting works the best.

Use the null for the newly generated lights and go to frame 1 and spin the lights along the Horizon 720 degrees and set it to repeat forever in the graph editor.

then set your AA level to Enhanced Low and activate dithered Motion Blur and play with the AA until you are happy with your shadows.

Oh and be sure to just follow the instructions here...they are self explanatory.
LightGen instructions (http://www.ict.usc.edu/~jcohen/lightgen/lightgen.html)

I use point lights for what it is worth.

this is a lightgen derived render:

Hey thanks for the reply policarpo.. i have been getting just plain white lights from my lightgen renders.. I must be doing something wrong.. I think i might try to point lights.:) How goes the MB progress?? I'm still stuck on that subject..

oh...be sure to set your light intensity to something like .1 or so...or just render it to Image Viewer FP and adjust your white and black point.

you're getting white lights because the intensity is way too high.
