Some changes were made to the exporter since the version that comes with Ogre 0.15.1 and that includes some changes on the texture coordinates export. So it is likely to solve your problem.
Thank you!
However i am using the 0.1.5.0,
i downloaded from the Ogre3d.org Tools Directory
isnot it the latest version,
would you please provide me a link to download the latest CVS?
There is no direct link to download cvs. That's what CVS is all about. However, you can download the daily snapshot of Ogre CVS in the download section. It will be a pretty big download just to update some little scripts but it will work.
You can also try to download the scripts at this url. This is my own personal version. It should be up-to-date with CVS and it will be way lighter to download.
