Hi Ming,

Changing the file extension from .rgb (Which doesn't support
compressed textures) to .dds (which does) is the perfect solution in
your case.  .dds is a much more complete image file format for modern
graphics needs - it supports compression and mipmapping, while the old
.rgb format is ancient and only supports non mip-mapped non compressed
images.

Robert.
