Hi Mark, what are the particular issues that you are running into with Modo? Quite a few people use Modo to render MoI objects. Maybe the things you are running into can be solved.

One particular note - if you're using Modo 601 then you should set the export options for MoI under Options > Import / Export > LWO options > "Vertex normals style" to actually be "LightWave v10" and not "Modo", since in the new Modo 601 version they changed how they read vertex normals in from LWO files.

That "LightWave v10" option for LWO normals export is available in the MoI v3 beta.
