Hey estheray,
I'm not sure wich Casino P7 you mean, are you talking about my other product "The Casino: Poker", or some different product.
I must say that in this product there are only props wich are uv-mapped, ready to import in your scenes. I haven't really thought about creating alot of PZ3's for my products, but you have a strong point. I will look into creating some pz3s file for this product, wich I will send you by PM as soon as you bought it!

on the other hand, my products are always very easy to use, as they are props, just choose them from directory, and place them in place, ready to render.

Have a great day!
Peter
