Decent Lighting the Easy Way
This is for RKane, who asked how to improve his lighting in order to sell a product, and for anyone else with the interest. I always feel a little uneasy doing public tutorials, because I'm usually instructing on something that other people are better at than I am. The fact is, though, that those people aren't always going to have the time or interest, and I can still help a beginner without being, well, mattymanx. ;D For some examples of very advanced and gorgeous lighting I point you to his deviantart page. For now, let's look at lighting in DS4. This should work in DS4.5 as well.
The picture attached to this first post represents the DS4 default lights and render settings. Notice how the picture looks gray and dull. I've heard people claim you should offer a render of the default lighting with a product in order to prove that it works. This is a terrible idea for several reasons. The most important is that nothing looks its best in default, and renders sell product. The second is that default lighting can mask normals direction problems in a mesh that make it totally unusable under UberEnvironment lights. Third, you don't want to even pitch to customers who regularly render under default only, because you don't want your name on the credit lists of renders that you know are going to look terrible. That's not a good advert for your product.
The character is SAV's Spartacos, the figure is a Genesis character dialed from D3 and M4 with one of RAMWolff's free faces, and the pose is by DZheng. All the goodies he's wearing are by me.
