So I’m trying to swap from a single texture on a cube to a mapped texture that will cover the whole cube based off different textures for the top and bottom and the same for the sides. I had the textures working with the last way of setting textures but now when i try to create the cubes they just turn out plain white. Any idea why this is happening?
Here is my code:

Thanks guys.
I’ve never worked with cube maps, but does [icode]glEnable(GL_TEXTURE_CUBE_MAP);[/icode] before binding your texture help?
Maybe you need to activate the texture whenever you bind it (when uploading texture images and rendering)?
glActiveTexture( GL_TEXTURE0 + unit );
glBindTexture( GL_TEXTURE_CUBE_MAP, tmp );
where unit is the texture unit (probably zero if you’re just using one texture unit).
Also the values passed into the upload class seems incorrect, e.g.
glTexImage2D(GL_TEXTURE_CUBE_MAP_POSITIVE_X, 0, GL_RGBA, decoderTop.getWidth(), decoderTop.getHeight(), 0,
GL_RGBA, GL_UNSIGNED_BYTE, bufSide);
mixes the side texture buffer image and the width/height of the top image, though I doubt that’s the main problem, would probably just cause odd results rather than all white.
You could also try GL11.glGetError() after each of the main steps to verify the code.

this line worked to bring the textures onto the cubes, however it now looks incredibly messed up.
