As far as I know in propack is nothing new for lights and rendering.I dont know if the images you saw had none,little or much postwork in photoshop or another program. There are some lightpresets at the marketplace that may help you. My own experience is USE THE SPOTLIGHTS.play with the falloff,angel and color and you can get good results. And put the final rendersize to 1000 x1000 with 250dpi and save your image in *.tif not *jpg.if you need *jpg, do it in photoshop or similar
