Hello... I have a big problem with a SkyBox. I switched off the Depth testing and so on, but it still looks as if the sky is very near. i've no idea anymore. Any help ???

    
const int   QuadDir[5][4]   = { {7,6,2,3}, {1,2,6,5}, {0,1,5,4}, {4,7,3,0}, {3,2,1,0} };
	
	const float SkyCoords[4][2] = { { 0.5f / 256.f, (256.f-0.5f) / 256.f }, 
									{ (256.f-0.5f) / 256.f, (256.f-0.5f) / 256.f },
									{ (256.f-0.5f) / 256.f, 0.5f / 256.f },
									{ 0.5f / 256.f, 0.5f / 256.f } };

	glDisable(GL_DEPTH_TEST);
	

	for (int q1 = 0; q1 <= 4; q1++)
	{
		glBindTexture(GL_TEXTURE_2D, skytex[q1]);
		glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP);
		glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP);
		
		glBegin(GL_QUADS);
		
		for (int q2 = 0; q2 <= 3; q2++)
		{
			glTexCoord2d(SkyCoords[q2][0], SkyCoords[q2][1]);
			glVertex3fv(SkyVerts[QuadDir[q1][q2]]);
		}
		
		glEnd();

	}
	
	glEnable(GL_DEPTH_TEST);

perhaps use a larger FOV in your camera.
use diffeent skybox textures.

yeah using larger FOV values in your glPerspective procedure, or larger textures for that matter could make the skybox look less blurry and near.

Well, changing the fov value doesn''t bring the result I want.
I tested it, but it looked near (fov: 90).

In any other tutorials i downloaded the skybox looks great. But if i copy pieces of the tut source into my one, it has the same effect like my skybox. I also changed the textures, but no effect.
