I want to use POVRay to do some pre-computed baked in radiosity solutions.

What I need to be able to do is upload my entire 'game level' into POV Ray but,
when I render, render only a sub-section of that game world.

Since the 'scene' seems to be a global concept; I'm not quite sure how to have
it render only a sub-section of the scene.

Could this be done by setting a no-draw material property on the portion of the
level I want ignored while still having the raytracer take the entire world into
consideration for shadows, etc.?

I'm brand new to POVRay so forgive the naivete.

Thanks,

John
