Eh, shadow maps suck and all they do is make your images "dirty" mostly and cause unnatural "shadows". I use Raytrace shadow, only 1 distant light and 1 specular light for natural 1 light scene, I add lights if there are other lights needed, such as for photo studios where they have some soft lights and stuff going all around.
Also loading too many lights tend to kill the occlusion effect of UberEnvironment as well as (as what I notice) blur up your image a bit. If you're gonna load so many lights, there's no use for UberEnvironment (except HDRI color)
You want good lights set up properly (especially for outside), go get "Cloud Nine" by DimensionTheory at Daz. You know how my renders come out,, they always produce proper shadows and looks more natural, and arn't "so bright" all around unnaturally. I always use his lights (but I play with settings sometimes with the HDRI effect and brightness and all that), crystal clear with proper shadows/shading/occlusion shading.
This image looks ok but too bright all around unnaturally (unless you're going for a "photo shoot session" look) and the occlusion shading seems to be missing.
thanks for your comment, well that render was only for my "naughty" purposex, I mean, PURPOSES!!, yeah XD, not intentionally for exhibition, for images like that I prefer use conventional lights, faster and more control, ya' know how I work with Big League renderers like Modo,Maxwell and LuxRendah.
Ah, you didn't download the latest update of LL1 The .tifs I included weren't made with the HDR to TIFF app cause I didn't like the results it gave, which is why you get an error (that does not affect your render AT ALL). If you don't want to reset your downloads you'd have to replace the tifs manually with the jpegs included. And of course, thanks for using my lights
