If I set Unit Scale to
1 and Length to
Miles, then insert a 1 mile by 1 mile cube, I run into all sorts of problems.
First the camera only zooms out far enough to have five of these cubes visible at once. But now, I can't even do that, as there seems to be some clipping related glitch that makes it impossible to see the cube from outside it. Zomming in and out sometimes causes weird triangles to appear. (I'm not really sure what is happening).
I would like to work in real-world units and have Blender do the scaling, but I'm not sure how to set up the file for a large scale scene.
Let's say that I wanted to insert a sphere that is 8,000 miles across, and have Blender behave just like it's a 1 meter sphere in the default file.
After setting units to "miles", how do I set "unit scale" and setup the camera so it "just works" in a sane way?
