[Bf-funboard] Limits on size

Sounds like the classic "from earth to ant"-problem to me. For scenes 
with extreme zooms like "from kilometers to millimeters" as you describe 
it the use of one gigantic scene is probably the wrong approach. I had 
to do two such animations in the last months (one zooming from a waver 
to a microchip and one zooming from a 7cm casing to, well, a biological 
microchip). In both cases I created two scenes and used compositing to 
add them together seamlessly, which AFAIK is the method of choice for 
this kind of task.

Another thought on the way: Even if you succeeded in creating the 
gigantic scenes you'd run into real trouble when it comes to animation. 
The IPO-curves for camera movement become mostly unusable when moving 
from gigantic to minimal proportions, I've had my experiences.

If you really want to do something cool write a python script to blend 
camera motion in different scenes an scales, that would come in handy in 
countless situations.

Greets,
