Hello, I'm doing some experiments with the built-in SubD conversion (from OBJ file) in MoI.
With a low-poly OBJ model imported, the SubD conversion creates very smooth surfaces.
However, it tends to convert medium-poly or high-poly OBJ into coarse, somehow faceted, surfaces.
The 1st screenshot shows two OBJ models. The 2nd screenshot shows their corresponding converted SubDs.

It maybe hard to see the difference by looking at the screenshot. But upon close inspection the roughness SubD surfaces are quite apparent.
I have attached the 3dm file below.

Is it a limitation of the built-in SubD conversion? Like it could only smooth simple polygon?
