textures and surfaces

Hi,
I have two surfaces that I would like to texture.The texture, however,
needs to cover only half of the surface in width but the full height of
each surface. I am not sure what is the best way to do this. Any help is
appreciated…

Your best bet might be just to draw four polygons instead of two. It might not be the fastest solution, but the simplest solutions are usually the best.

Map the first poly with the coords:
(0,1),(0.5,1),(0.5,0),(0,0)
and the second:
(0.5,1),(1,1),(1,0),(0,0)

Notice i’ve only used half the width of the texture on the U coords for each poly. That should do the trick.
