Well, no matter what we try - we tried both 2.63 and 2.65, we can't get it to be in the right place. The camera is simply too close to the object to render it at the desired proportion.
To test, this is BR 304 appended (excluding cameras and spheres, etc - tried with, too, but there was no improvement) to the template and rendered with no other changes:
And finally, a new attempt at the 4-COR (fixed the roof, at least...). But it's still the wrong proportions.
We're obviously doing something wrong here, but we're having trouble wrapping our heads around it. Do we need to change settings for the camera, and if so, to what?
