Not directly related to your problem, but this is worth a look for anyone messing with the camera range:

You should also take a look at:
EntityAutoFade
CameraClsMode
You will probably be able to do what you want with either of the above. CameraClsMode is useful for doing multiple renders, adjusting the CameraRange for each one. Multiple renders will also be useful for your skybox (which can be quite small if you render it first).
