Hi Dave, also re: n-gons into Modo.

From a different post you mentioned that you were using .obj format to go into Modo?

I'd recommend using .lwo format instead - that will likely eliminate the problems you are currently seeing.

Modo's OBJ importer has some issues with n-gons specific to the OBJ importer itself.

If you use LWO format to go from MoI into Modo, you will avoid those problems that are specific to the OBJ importer and you should see better results with big n-gons especially.

You still can occasionally get an n-gon that Modo's core n-gon handler does not like (which is what I was referring to previously), but that is pretty rare.

Sorry I didn't mention this earlier, I just assumed you were using LWO format.

There are some other details about this problem with Modo's OBJ importer on the Modo forum here:
