Just realised how un-useful that post was
, heres a stack trace that came out:
faceSize is set to 2 for triangle strip arrays. The number of faces is caculated like this:
4 verts / 2 = 2 faces (yep)
5 verts / 2 = 2 faces (it'd be 3 faces wouldn't it?)
6 verts / 2 = 3 faces (4 faces?)
Maybe I don't understand what a Triangle Strip is properly. Actually, if you consider the index array the above isn't going to be right, um.. sorry was trying to be more help but appear to have made it more confusing.
