Hey Guys,

I am drwing a cube with a texture on it using index buffer. Unfortunately, the last side of the cude isn't showing the texture correctly... the 5 other sides are showing it fine.

I've checked the texture cordinates for the last 2 hours... don't know what the problem is sadly.



This is the bulk of the code for the cube.

It has to be a texture cordinate problem?

Why are you reusing vertices for the last face (the last index buffer block)? I coldn't be bother to look through all the Tex coordinatess but I guess the problem lies there.

Because I am brainless it appears

HEHEHE... yeh that was the issue... don't know what I was thinking

But its fixed now

Thanks heaps
