Hi Edwin,

> Modo 301 does support vertex smoothing and it looks great.

That's great! That will be a huge improvement for rendering CAD models.

The only problem is that currently there is nothing in the LWO spec for storing vertex normals inside of a LWO file, you will only currently get them in an OBJ export.

With their new version's support, they must have some kind of extension for the LWO format for storing normals in the LWO file. If I can find out the details of that format extension, then I could write the vertex normal data to LWO as well.
