Sunlight overload!

This pic is of the Enterprise-E.

(The grey on the upper part is some rings I put around the planet.
They are normal)

The angle toward the sun, but in Earths shadow. Its like this with all ships I have, but not planets, moons, and asteroids. Only ships. Why is this?
I adjust the albedo and the ambient lighting, but that dosent seem to work.

Is it a Celestia problem?
Should I download a different version? (I use Win32 1.3.2)
Or is it a PC problem?
(Specs:
Vendor: Microsoft Corporation
Renderer: GDI Generic
Version: 1.1.0
Max simultaneous textures: 1
Max texture size: 1024

Supported Extensions:
GL_WIN_swap_hint
GL_EXT_bgra
GL_EXT_paletted_texture )

Whats up?

The current version of Celestia only casts shadows by spheroids onto other spheroids. 3D models can neither cast shadows nor have shadows cast onto them. :(

Maybe in a future version...

Not what I ment.
I ment how can I make it
so that every ship is in color
and not black and white?

Thats all I see is the basic shape of a ship
and the side closest to the sun is white,
and the side thats away is black.
How can I "disable" this?

Do you have "ambient light" turned on in the Render menu so you can see the shadowed areas? Try turning it off.

I think it's really a bug in Celestia. :( It's drawing objects that orbit a planet so that the highlighted areas are much too bright, especially when the basic color of a model is light to begin with. Objects in orbit only around the sun aren't drawn so bright.

It seems to help if you turn off ambient light. The software controlling most graphics cards includes a gamma adjustment that can help, too, but Microsoft's software OpenGL doesn't. (Another reason to consider upgrading the graphics on your system.)

p.s.
With ambient light turned off, the sides of objects that are turned away from the sun should be black. There's no light getting to them.

Of course, if they're near the sunlit side of a planet or other large object, there should be additional light getting to them from the planet, but Celestia doesn't even try to draw that.

I found a workaround changing visions from 1.3.2 to 1.4.0pre6.
By pressing shift+[ or shift+] you get these effects...

On my system it looks cartoony, but it got me foreword in my fix.



Semi-related note: How do I turn the sun down?
Like, does it have a dimmer setting that I can
mess with in the data folder?
