Title: Skybox fixes
Post by: Udi on December 16, 2010, 11:01:42 PM

A small skybox fix package, the next version of the nebulae pack (http://openarena.ws/board/index.php?topic=1945.msg27279#msg27279). Thor001 found a bug in that pack, it will fix that, plus the space1... textures are fixed too, and the oa_pvomit texture were polished a bit: JPG artifacts removed and more seamless edges.

Question: space1_bk, space1_dn, space1_ft, space1_lf, space1_rt textures are exactly the same, could we keep only one and refer to that one with shaders? All the nebulae textures are also based on the same space image, but I would like to keep space1 and nebulae separated, if we change one, the other shouldn't be affected.

don't think that's possible. this is a snippet from the q3a shader manual describing the farbox in a skybox:

Code:

3.1 skyParms <farbox> <cloudheight> <nearbox>

<Farbox> Specifies a set of files to use as an environment box behind all cloud layers. Specify "-" for no farbox, or a file base name.
A base name of "env/test" would look for files "env/test_rt.tga", "env/test_lf.tga", "env/test_ft.tga", "env/test_bk.tga",
"env/test_up.tga", "env/test_dn.tga" to use as the right / left / front / back / up / down sides.

as i understand you need all these files. imo it's not worth the effort to go around this just to save up on a couple of images.

I see, I thought that it looks for a shader definition first, so we can make something like this:

Code:

env/space1_bk {
	{
		map env/space1
		rgbGen identity
	}
}

But I've tested now, and it's ignored.

Do these fixed textures have ever been submitted to the SVN commits thread?

(Sorry for resuming a very old thred.... I found this thread by googling infos about skyparms...)
