The OGRE team are very pleased to announce a partnership with SoftImage, which has enabled the OGRE team to join the developer program for SoftImage|XSI 4.0. Thanks to this partnership, we will be developing an XSI v4.0 exporter over the coming months, and this has been added to the Roadmap for 1.0.0 (although early versions are likely to be available for separate download before then).
The OGRE team would like to extend their thanks to SoftImage for their support. Further announcements will be made as the exporter progresses.
