Hi Mike,
The osg::Texture class has a method:
/** Sets whether to force the texture to resize images that
have dimensions
* that are not a power of two. If enabled, NPOT images will
be resized,
* whether or not NPOT textures are supported by the
hardware. If disabled,
* NPOT images will not be resized if supported by hardware. */
inline void setResizeNonPowerOfTwoHint(bool flag) {
_resizeNonPowerOfTwoHint = flag; }
The can be used to hint to the texture whether to do the rescale or
not. For compatibility with old hardware this still defaults to
false, and the OpenFlight plugin doens't have an option for setting it
on Texture's it creates. You can however, traverse the loaded
subgraph and set the above hint on all the texturtes you find.
Robert.
