This may not be a bug, but I thought I should mention it in case it's an oversight.

When running Celestia v1.3.0pre5.1 on a Ti4200, only 4 rendering paths are available: Basic, Multitexture, "NVIDIA Combiners" and "NVIDIA Vertex programs and Combiners". "OpenGL vertex program" and "OpenGL vertex program/NVIDIA Combiners" are no longer available.

It seems to me that it would be useful for testing to be able to select the OpenGL ARB routines by themselves even when using an Nvidia chipset.

That's what "OpenGL vertex program" is: the ARB_vertex_program extensions plus ARB_texture_env_dot3 for bump mapping. The register combiners path is preferred though--it's faster, and gives better quality.

Chris,

My point was that "OpenGL vertex program" is no longer available on my Ti4200. For some reason it's being skipped and only the paths that include the Nvidia combiners are listed now.

Oops! I completely missed a period in your post and misread the message. Check celestia.cfg and make sure that this line:

IgnoreGLExtensions [ "ARB_vertex_program" ]

is commented out. I screwed up and left it uncommented when I packaged 1.3.0pre5.

Chris,

Thanks for reminding me. I'm sure that's it. I'll confirm it this evening.

Yup. It was. Thanks!
