I let it display the readme and start Celestia (both selection boxes were checkec by default) with no obvious problems.
Io appeared OK.
Select Earth
Goto Earth
OOPS!
Symptom: The Earth appears on screen with a totally black surface.
Cause: The wrong Texture is enabled in /data/solarsys.ssc as shipped
Code: Select all
# Texture "earth.png"
Texture "earth8k.dds"
Unfortunately, but for good reason (size), earth8k.dds is not included with Celestia.
Cure:
Removie the # from in front of the png declaration and placing one in front of the dds line fixes this problem.
Code: Select all
Texture "earth.png"
#Texture "earth8k.dds"
Things to note (presumably not bugs)
"Use Pixel Shaders" is enabled and *cannot be disabled* from the Render menu.
"Use Vertex Shaders" is *greyed out* and cannot be selected.
Although "Use Vertex Shaders" is greyed out in the menu,
Ctrl-V toggles among the new "render path" options.
Additional symptoms when using the wrong surface texture:
Render path: Basic: earth is pale blue sphere
Render path: Multitexture: earth is pale blue sphere
Render path NVIDIA combiners: earth is pale blue sphere
Render path OpenGL vertex program: earth is pale blue sphere with a specular reflection highlight
Render path OpenG vertex program/NVIDIA combiners: earth is dull black sphere
