Sergey Tyapkin released another update to his UV tool for Blender.
For those of you who missed the news, Zen UV is a set of tools for UVs in Blender powered by an intuitive system created by professionals that allows saving time on creating UVs.
There's Smart Zen Unwrap Operator to mark selected edges/faces as Seams and/or Sharp edges and Unwrap by Marked edges after. There's also a Powerful Marking System to mark Seams and/or Sharp automatically by angle, by existing UV Borders/Sharp Edges, and manually.
- Powerful Stack System. Stack and Unstack islands automatically and manually. Extremely useful for increasing Texel Density and baking. It works using Zen UV Dynamic Library (supported on Windows, Mac OS, and Linux platforms).
- Copy/Paste operators. Copy/Paste parameters (TD, Position, Size) between Islands/Faces.
