They are not invalid, decimal 33776 is hex 0x83f0 is GL_COMPRESSED_RGB_S3TC_DXT1_EXT. In the process of converting to .ive they have been compressed to speed up texture upload. As far as I know no image exporter supports writing these compressed images. You could render the texture to a framebuffer and read that back... :-/ /ulrich _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
