Thanks for that, just what i wanted … while im here, i hav another question…Can i use a VBO to store data to be used as a vertex attribute for GLSL? because i hav Tangent and BiNormal data stored as VBO’s, and i was wondering if i can use Vertex Attributes, or do i hav to use them as TexCoordinates??

It’s up to you
You can use vertex attribs and you can you texture coordinates when working with VBOs. Both will do it.
