Hey, Right now, I am working on my first 3Dish engine. It is a tile 3D engine. I have it set up so that every texture has a Index buffer and Vertex buffer associated with it. That way I can draw every polygon with one texture at a time.. Is this a good approach, or will it not work? Thanks in advance...

Unfortunately, the SetTexture() function is quite computationally expensive. Depending on how many separate polygons get separate texures, you might run into some performance problems. Just make sure to batch your textures together so that you don''t have any redundant duplicates. Draw all the tiles with tex1, then draw all the tiles with tex2, and so on so that you can minimize the number of SetTexture() calls.

I think you misunderstood my question, but you still answered it.

Thanks for the reply.

Later, James.
