Planet02 distance limits?

I'm trying to put a moon in a scene I'm working on, and am using real life units to generate it's radius and distance from Earth. The problem is, is that there seems to be a cutoff point on whether TG actually renders the secondary planet, which seems to be around 2e+008 and 3e+008. Does anybody else have this problem?

It's the same thing for a sphere too. Am I doing something really daft here? Would someone mind and have a quick look?#

Just to add, I'm looking at frame 694 in the animation, I'm hoping the scene saves the current frame.

This area in the camera tab seems weird.

Oops, I thought I'd saved the crop of the screen area, not the whole screen...

Thanks for having a look.

You do need to be looking at frame 694, as this is where I was setting things up (there are 5 shots on that timeline).

I wouldn't worry too much about the rotation, I think it's consistant through out, it's how the script in max baked the animation to a free camera. It shouldn't have any baring on the specific problem of the sphere and moon switching off between 2e+008 and 3e+008 meters.

I do not have the animation package. But I did a quick render. The result was a black screen. There may be camera clipping limits, too much calculation otherwise I think.

Adding a 2nd planet to the default scene may give you an idea of how distant things can be.

I think I know what your problem is. In the Objects tab, find the Background object. Increase its radius from -2e+008 to -2e+010. I think your moon is disappearing behind the background.
They just issued a tornado warning and said to stay away from windows. Does that mean I can't use my computer?

Genius! It's exactly that. ^^
I just tried bg = '-3e+008' to create a huge expansion and the planet and sphere both reappear instantly.

Good thinking, man!

Legend mate. That's exactly it. Thanks.
