Quick upload on how HDR lighting works in a scene...

I think this is the way to setup to good lighting. Better such studios with a closed box containing 3 till 5 lights. This blend is less noisy and renders faster. Though I brought the bounces back to just around 12. Renders much faster and difference is not that big.
Thanks Nick! =)
I've been wanting to use HDR lighting.
