Hi Sergey,
You suggested change looks reasonable. Curious that others including
myself haven't spotted this error so I can only presume that quite a
few GLES implementations do indeed included support for
GL_MAX_TEXTURE_COORDS. Once you have the code working cleanly could
you post the modified file to osg-submissions.
Thanks,
Robert.
