Hi yophie, yeah the Blender import script only worked in a fairly old version of blender (version 2.49 if I remember right), and not with current versions so I removed it.

See here for some information on a more recent modified script that I think works with current Blender versions:

If you do need the old version for some reason, here is the information that used to be listed on the Resources page:

Anthony D'Agostino wrote a custom blender .lwo import script to enable exporting data from MoI to Blender while preserving the accurate vertex normals to get high quality smooth shading. To use the script, you need to turn vertex welding off when you export from MoI - in the Mesh options dialog, click the small arrow in the lower-left corner to expand to detailed options, and uncheck "Weld vertices along normals". Getting the accurate normals makes a significant difference in increasing render quality, it eliminates small shading glitches that happen when the shading normals are created just from averaging adjacent polygons. More information in the forum post: http://moi3d.com/forum/index.php?webtag=MOI&msg=979.1. Also see this other forum post: http://moi3d.com/forum/index.php?webtag=MOI&msg=3583.1 for a link to Anthony's custom build of Blender that does not throw out normals and recalculate them for rendering.
