Hi David, which importer are you using on the Blender side, the default LWO one?

I don't think that one knows how to import vertex normals - getting in the proper vertex normals is the best way to avoid shading problems.

Try this instead - in MoI set "Output: Triangles only" (or "Output: Quads & Triangles" should be ok too).

uncheck "Weld vertices along edges".

Under Options > Import/Export > LWO options, set "Vertex normals style = Modo".

 

Then when importing into Blender, instead of using the default LWO importer, instead use the one that Anthony wrote which you can find here:

That one will bring in the vertex normals and should help to make a much higher quality shading. The only problem with it is that it does not bring in any material/style information, just geometry only.


If you want to bring in styles and materials you can try OBJ format instead, but there seems to be some different problems in Blender's OBJ importers, one of which is that the standard one throws away vertex normals instead of bringing them in. I have a modified version in this thread here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=3164.11
which has been changed to keep the vertex normals that are loaded in which seems to help a lot. But I seem to remember Mark Brown running into a variety of additional bugs in the Blender OBJ importers for handling materials in OBJ files as well though.
