Vertex declaration

Have you figured out how to add multiple texture coordinate sets to a vertex declaration? Simply adding another one, as you do in Direct3D, causes OGRE-D3D9 to crash and OGL to break texture coordinates, so there is a knack to it. A short discussion on this would be suitable to for this tutorial. Mikademus 20:27, 21 July 2008 (BST)

Do you know that VertexDeclaration

:addElement has an optional parameter ? It's the index of the semantic you want to use (default to 0).

If you want to add another element with the same semantic, you'd want to increment this index. Archangel 23:00, 21 July 2008 (BST)

I baked that information into the step-by-step section of the article and added a texture coordinate set to the example. It wasn't covered very well in the API so it has its place here. Mikademus 14:55, 22 July 2008 (BST)
