Hi and welcome!

Learning Poser can be frustrating, particularly as different merchants package things in different ways; why a readme file is ever positioned inside a runtime folder defeats me!

But there is help at hand; if you ave Poser 7, you can shortcut the learning process by buying Denise Tyler's 'Practical Poser 7'. It's a great way of learning quickly.

BTW, Poser Lighting and renderer are unnecesarily difficult , weird and erratic, and the latter is way too resource hungry  IMHO. Many of the better pics you see in the Gallery have been lit and rendered in a different app.

Have fun!
