Hi there.
I'm relatively new to 3D Modelling and I've got a question regarding Box Unwrapping in 3Ds Max 2017.
The doesn't work the way it should I guess. The Box Unwrap behaves the same as I would use a Plane Unwrap from all 6 sides and put them in the UV Space.
As you can see, each side is separately in the UV Space.
As far as I remember in earlier versions a simple cube was unwrapped as a cube(blue sketch) and not every single side separately (I can be wrong though, haven't worked with UV Mapping alot)
Slightly related:
Sometimes when I apply the UVW Unwrap Modifier, I can't edit anything. I have to collapse the stack first and reapply the Modifier.

If you want an unfolded UV, use Pelt. Or use Planar on the whole thing, then break the edges where you want the seams, then Relax.
When you can't edit anything, this usually means the modifier stack was in Sub-Object mode when you applied the UVW Unwrap modifier. Read up on the modifier stack in the help file.
