Sorry Matt, my mistake- I read the rules but I have mistaken a word:
It's written "Choose between 1 and 5 locations (camera positions) in your scene."
I read: "Choose between 1 or 5 locations (camera positions) in your scene."
A second one is absolutely possible but 5 would have been too much.
It's because even if you would render the big versions, I want do render it once on my own to check that (most) of the details are ok. E.g. I very often had nice looking 1280x720 renders but in 1920x1080 they look catastrophic.
Oshyan, that's interesting, thanks for the information.
