UV Smoothing- Preserve Edges and Corners distorting circular edges.

[armstrongdavid744]

Hi there.

I'm experimenting with modeling at a lower resolution and subdividing at render time. However, I'm running into difficulties with UV smoothing;

Below are UVs from a hollow cylinder and since the "Preserve Edges" UV smoothing option rounds everything including the outside of the cylinder, it looks like I'll need to use "preserve edges and corners". It fixes the outside of the cylinder but the circular UV shell edges now manifest a single creased vertex which isn't smoothed.

Is there a solution/workaround for this?

Any help would be appreciated, cheers.
