Maybe we are forgetting that we don't all use the same graphics card, or display resolution. What I render on my computer probably looks totally different on someone else's, even using the default Poser lights. And monitors differ ... so unless you have the exact same equipment as the person you made your purchase from, AND the same graphics card, AND the same display resolution, etc.... your render cannot possibly look exactly the same.

Some people dream of worthy accomplishments,
While others stay awake and do them.

I am a dreamer
