Two subd bugs

  1. when reflect is applied, I get weird display behavior.

  2. When moving vertices the subd, it switches to smooth until released when in box mode, or to box mode when in smooth mode:

Can replicate both bugs, but the second only once per geometry and only just after removing symmetry.

This happens to me also after switching from box- to smooth-mode (only 1 time after mode switch).
But I have experienced that this unintended behaviour can be very usefull!
Have your object displayed in smooth mode, but while dragging a subobject of the subD the mode switches automatically during dragging to box mode, and when you release the mouse button it goes back to smooth mode (or opposite).
Only because I ran into this I experienced that it works very well to deform in box mode and see the result in smooth mode directly.
Would never had thought of it, but now I want it as a “deformation mode”, not just one time as it is now, but as long as I want it.
Can we have that? Please?
