Hi Celestians!

I'm having the same problems with my ATI 9600 graphic card.
I have the newest ATI drivers (4.10) and my favorite OpenGL benchmark test says that my card is fully compliant with OpenGL 2.0.
In spite of these facts Celestia doesn't work in OpenGL 2.0 mode (pressing Ctrl-V a couple of times in my PC).

So I was going to create a new Topic with this title

"Simply Red" :lol:

just because the earth and the moon (the only planets I cheched!) become completely and simply ... red.

But you were faster than me!

Today at office I downloaded the latest .vp and .fp shaders files from CVS, just to see if at home everything works.

Thanks for your attention
Pierluigi

Hmm . . . another slight difference between ATI's and NVIDIA's GLSL parsers. It's an easy fix; I'll have a patched version ready later today.

The red color is deliberate--it's meant to indicate in an obvious way that there's a problem with the shaders. The OpenGL 2.0 path doesn't use the .fp and .vp files in the shaders directory. Instead, shaders for different lighting situations and surface properties are constructed at run time by Celestia.
