i want my sky to look real and dont wont the corners of the boxes to be visible so should i use skyspheres instead.you can basically make your own skyspheres or cubes by using primitives and positioning them around the matrix and texture them, if your using a cube or sphere if you enlarge it bigger then the character wont i be inside and collided with it.

Don't think it's a problem, but I don't agree with the statement.

Skyspheres are higher in polys. It is difficult to map a texture onto a sphere so that you can't faintly see the edges of each face. However, with a skybox, simply use textures that account for distortion created as the distance from player to face greatens. Simply render a background from 6 viewpoints and the edges will appear visible. Terragen is great for this. Think of Half-Life (though there were a few occasions where Valve didn't render correctly and the edges are slightly visible).

u could make a hemisphere with 40% of the bottom deleted.

you could make 3 spheres with different textures on them to represent cloud layers or the twinkle of a nights sky.

I dont like using sky spheres, they tend to slow the game down. I always texture the backdrop with a seamless cloud texture, fog the matrix a bit to match the sky colours. then add a little code trickery to make the sky pan in the opposite direction your turning. its quick and painless.
