I`ve attached one of objects from Modo.

I can`t share whole set of objects without rebuilding it becouse of NDA.

That attached mesh is a good example. I model with subd many hard surface models during my regular daily work. To do hard edges in subd I have to give additional loops near hard edges which cause such a tight bendings (to force hard edges there). Doing whole subd model without additional loops for hardening edges is very rare. I can`t remember even one of my subd meshes which had only smooth surface without additional loops near hard edges so it`s a big limitation.

This is example: I`ve doubled same mesh which I`ve attached. One cube has got subd turned on and the second has got subd turned off.



Giving those additional loops is a way to create demanded shape in subd.


Other thing is subd levels. | may change subd levels in Modo but I can`t export it with obj :) So in my opinion those obj are exported as low poly cage without info about subd smoothing. I`ve looked that kind of info in notepad but those obj don`t have any info about subd levels so I can`t change it to lower level without doing it in MoI (becouse it`s imported on lowest level without any smooting info).

Thanks Michael for helping me out with deeper understanding of that workflow.
