{mosimage}A new version of the XSI exporter (for v4.2 and v5.0) is now available for download from the Tools Section.
This version (1.0.6a) is functionally identical to the 1.0.6 version
released a week ago, but has been considerably optimised such that it
exports meshes about 15 times faster than before. For those of you with
large models, this is definitely worth the download.
