So I'm wondering if it's possible to create the scene for a level like in Baldur's Gate (where some of the maps can be 6000x3000). The thing is, they're all at a constant look-down angle and position no matter where you are on the map (effectively an isometric map, although not a tiled one)
Would creating an orthographic camera be sufficient for this ? If not, would it be possible to traverse the camera over the terrain and stitch renders together somehow ?
In case it's not obvious (as if!) I'm new to Blender, although I've written a fair amount of code in my time...
 So apparently I’m supposed to add new information to the post, not reply inline :) To clarify, what I’m trying to do is render a large isometric-perspective (well dimetric really, I guess) map, using world-creator to create the mesh, and blender to do an orthographic-camera render.
I’ve been doing some more reading and it seems if I set the camera look-down angle to 30 degrees, I get my nice 2:1 dimetric scale, and I can use a sun lamp to give consistent shadows across the scene.
I’m still having mental difficulties grasping that it could, in fact, be this easy :) Those are bound to be famous last words :)
