Go to edit mode, and in the buttons windows, go to the edit panel (F9), and select all the vertices. Now click the “Flip Normal” button.

Here is a tutorial written by Social that you can find by searching “skybox” with the forum search tool:

http://www.blendenzo.com/tutSkyBox.html

It explains how to eliminate the ugly seams by doing a little image editing in MS Paint.

You can also use a skydome instead of a skybox if you like. There is a tutorial about that here:

I hope you find them useful.

I found that by reducing about .5 to 1 pixel at either end works fairly well.

If you’re lazy just use this http://blender3dtutor.com/modules/smartsection/item.php?itemid=10

I scripted a automatic skybox generator (well it just maps the 6 skybox textures automatically to a cube).

It’s pretty specific to how the files should be named however, since it directly follows up from the video tutorial on making the skybox textures from terragen http://blender3dtutor.com/modules/smartsection/item.php?itemid=9.

Also, you’ll need to download a divX plugin to view the video tutorial.

Note: These were video tutorials I meant to post up a long while ago, but didn’t since the site still lacks content.

thanks for the help, they work great. but i want to know which takes up more memory? a sky box or sky dome?

i dont want the sky to rob all my memory and make the framerate slow down. i want this game to be played by as many users as possible, so i need the one that saves the most space, (but still looks good.)

skybox if you want to use less framerate, skydome for a better look. You choose :smiley:

You will not lose a noticeable amount of game speed by using a skydome as opposed to a skybox.

In my experience, the real thing that would cause a change of speed would be the texture size. So a skybox and a skydome that use the same size of textures should run at almost identical framerates. Older computers will choke quickly if you use tons of 1024x1024 textures.

remember to turn collision off on the skydome and it won’t eat up much CPU

Hmm, also, you may have to parent the dome to the player/viewer so they cannot walk up to the sun and touch it, lol.

And then you need a way to keep them on the ground plane…not walk off the edge of the world.

You can create a steep hill on the edge they cannot climb, or an invisible plane around the world…with collision set.
