This has bugged me ever since I started viewing this gallery a year ago. It happens even with the best, most 'photorealistic' renders, and (for me, at least) COMPLETELY destroys the effect of realism. Real people have darkened nostrils. Poser people don't. I don't know if it's a bug in the software, or something that's just been overlooked, or what, but in almost every render I've seen, it seems as if the nose just doesn't cast shadows in the nostrils. It's an embarrasing glitch in what I would otherwise call an excellent modeling program. I'll admit, I don't have much experience in Poser, having only played with the demo. But how hard is it to fix such a (seemingly) simple thing? Please respond with any answers/theories/flames. I'm really quite curious about this.
