Well, my copy of Practical Poser 7 has arrived and it is quite a tome... lots in here to get my teeth into.

I haven't found much on Ambient Occlusion yet, though I'm sure it's covered.

BTW Deecey... did you notice my other post about the annoying while line where a dark shadow should be? Any ideas?

In answer to your question... both hard copy and electronic version are nice, they compliment each other.
You can take the book to a comfy chair for a read while having a coffee, but the electronic version is great fro searching for specific words/phrases.

Cheers,

Isaac.
