Quote - IBL is Image Based Lighting, available in Poser 6 and 7.

In the picture, you have the same model, with the same skin shader, in two different lighting environments. The IBL is from Danae's Manhattan package. Complex lighting system comes from Orion's London set.

Neither is better or worse, they're just different and used for different purposes.

Generally, in IBL good skin textures look better, but bad look terrible :)

Ariah do you do any commission work for character design as of now?
I got a good hang of poser but im afraid i can't do everything just yet regarding to character designing and lighting, and I am working on a comic but having lots of problems making each character look nice the way you do it. If you have any tips or tutorials you can throw my way or if you can offer some of your services if any, I'd be thankful.

Don't let failures get to your heart, and also do not let success get to your head.
