I am not sure why but with my laptop which has a x700 and my desktop which has a 6800GT I get two completely different skys being rendered. The code base is the same... I am wondering if it's a driver issue?

When you're creating your clouds texture, which internal format are you specifying ? On ATI, if you do not explicitely ask for a 32 bits one, you get a 16 bits one. You should probably have:

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, w, h, 0, GL_RGBA, GL_UNSIGNED_BYTE, data)

Y.

Sweet, it works. It was the RGBA8. Another example of ATI vs. Nvidia not having the same idea on how things should be done. Thanks Ysaneya
