Quote - Someone would have to do a tutorial on the GUI. I also tried the light emitting square and it didn't work for the render. The Emitter would have to be so close to my subject to light it that it would be visible to the camera. So I have these terribly sharp shadows and I'm not happy with them. I tried using a sun and & sky lighting instead but the amount of fireflies suddenly was insane and I didn't want to deal with them. I just exported and left it to render while I went to Starbucks and the grocery store.

Maybe you should read the "offical" docu about the LuxRender GUI, how to use "Tone Mapping" etc.
