3D Extreme Zoom-Out Mode?

[Crossroads]

Having to support so many units over three levels of 3D -- each unit with six different facings no less -- it's a heavy, heavy burden. Just gauging whether players use 3D Extreme Zoom-Out -- seems so -- and how much effort we would save ourselves if we jettison it. At this point, jettisoning 3D Extreme Zoom-out? Seems not.

Come to think of it, the units have only one bitmap file, with six facings, but without a different copy for each of the zoom levels. However, for terrain tiles, there needs to be a bitmap file for each one of them.

How does the engine scale the unit bitmap to each zoom level? And can it handle the terrain tiles the same way give a code change of some sort?

I mean, both are bitmaps. The other scales, the other doesn't. Can you get rid of the terrain tile zoom level bitmaps? That would be a bonus wouldn't it?

And if the unit bitmaps do scale, would they support other zoom levels as well: ie. a variable zoom? That would be great... Of course, I do not know anything about the engine, just speculating here...
