Hi Bob, there are a number of formats you can export from MoI that will import into KeyShot. In fact KS5 introduced 3DM support for MoI too and you can render MoI surfaces with no need for render meshes, just tell KeyShot to import NURBS data. Otherwise you can also use, OBJ FBX LWO STEP IGES 3DS (if you keep parts below 65536 polygons).
