Hi Wim, the new OBJ importer in v4 is not a general purpose importer that can read in any type of OBJ file, it is for converting OBJ files that are set up for sub-d smoothing.

So if you have a sub-d model you can use that to convert it to a smooth NURBS surface model in MoI.

If your OBJ file just contains regular polygon mesh objects and not ones set up for sub-d smoothing, that type of data is not good to import into MoI.

> where can I find a tut or user manual for V4?

There isn't one yet, I'll be working on that once the last beta is finished.
