Someone using ZBrush UV Master?

Hi!

Is someone using that for uv unwrapping? Is it much better than 3dsMax for that?

3ds Max will give you more control, if you are using 3ds Max 2017 they have also updated the Unwrap UVW modifier so it has a bunch of new features and more importantly it has a better flattening algorithm. Each method requires you to set the seams to split up the mesh.
