Hi Alex - I'm glad that you like MoI! :)

The SKP exporter is one of the new functions for MoI version 2.0, you can download the v2 beta to test the new functions from this page: http://moi3d.com/beta.htm

Also there is a patch for the current v2 beta to fix a mirroring bug:
http://moi3d.com/forum/index.php?webtag=MOI&msg=2177.10
You can apply that patch after installing the v2 beta to fix a bug in it.

There is also a lot of other new stuff in v2 aside from SKP export!

There are some notes on the new stuff so far here:
