So to clarify, rather than use the ortho setting, you are choosing the
camera angle setting and using a 1? Is that it, or are you doing additional
stuff?
I was playing around last night and was noticing that the creations weren't
always centered when POV rendered them. Typically, the upper left was cut off.
I swear I remember a previous version seemed to center the creations to
ensure the entire thing was displayed in the window.
Am I having faulty memories? Is there any way to automatically do this?
Thanks!
Jake
PS: Again, great product. I am having ALOT of fun with it!
