Can anyone give me an advice, how to make a nice looking and FAST background for 3D world? I already tried attaching a bitmap on a cube with center in the “eye”, but that does not give nice results.(looks too much like a cube, not like a background, maybe just badly attached texture)
Any advice is appreciated.

Do a search on skyboxes in here

You need to deform the textures if you don’t want to see that it’s a cube…
I looked for this but I haven’t found anything… try, however!
And if you find something… tell me!
