No earthnight lights

[Marty]

Ver 1.5.1

The files earthnight.jpg exist in each hi/med/low-res texture folders

Nightlights in menu is checked on

and

solarsys.scc has this line included under "Earth"

NightTexture "earthnight.*"

Any clues why no earthnight appears (worked ok in prev ver)

Which Render Path are you viewing?
It sounds like you might have selected Basic. Multitexture is required in order to see night lights.

Type Ctrl-V several times to Celestia to step through the Render Paths that it finds available on your computer.

Yep that fixed it.

Thanks again!

One other query.

Why does the screen fill with yellow on start up before snapping to normal space view?

I suspect this is because you start off right next to the Sun.

[selden]

That's the surface of the Sun.

The viewpoint always starts at [0 0 0], the solar system barycenter. It's just above the Sun's surface.

[Marty]

Yes I figured it might be the Sun.

Any way to avoid it? It's rather anoying.
Didn't happen in earlier versions.

Edit start.cel to specify whatever starting position you want.

[ajtribick]

It didn't happen in earlier versions because the Sun was artificially displaced from the coordinate origin (this being due to the way distance was stored as parallax - to put the Sun in the correct place would require a value of infinity to be inserted, which is somewhat larger than the maximum value you can store in a 32-bit floating point variable).
