This message is probably osg::Texture2D rescaling the image to a power of
two when the osg::Image assigned to it is applied to OpenGL. Setting the
the non power of two hint in osg::Texture can prevent this. It used to be
that OpenGL only support power of two textures so has remained the default
for the OSG. From the include/osg/Texture header:
/** 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; }
