Hi Erland, The OSG by default with use glu to rescale non power of two textures as required so you code doesn't need to do anything special. If your hardware supports non power of two textures then you can do:
texture->setResizeNonPowerOfTwoHint(false); This isn't on by default because some hardware announces support for the extension (it's part of OGL 2.0) but drops down to software rendering when you pass a non power of two texture, so its something to be cautious about using.
