thanks once more to all, seems i got it running.
had to install visualstudio 2013 as 2015 gave out an error.
i will definitely have questions on finetuning so if anyone mind sticking around i would be very grateful.
the cornell box project already has me confused. no idea why there are lights setup behind the green and red cards.
looks like something i would setup for faked bouncing.
also none of the lights seem to react to changing of any of the params except the intensity and hiding them in the world outliner does nothing.
the sci fi hallway on the other hand scene works beautifully.
i love it.
