Nightshade UV Editor 2.1.3 for Maya (maya script)

Hello Martin,

I've encountered some problems using the NSUV 2.1 and 2.1.1, exactly the same as described by Enfy in Polycount thread.

In short - with more complex geometry NSUV starts to lag with simple operations like Move UVs (using the Translate Tool). Happens in NSUV 2.1 and 2.1.1, not happens in 2.0.10.

Steps to reproduce:

1) Create a sphere primitive and give it 50 subdivisions in axis and height.

2) Open NSUV, go into UV selection mode, double-click any uv on the shell to select the entire shell

3) Try to use Move Tool immediately after selecting the shell. There should be a lag of a few seconds before the shell could be actually moved.

4) Increase in complexity of geometry will cause a matching increase in lag duration.

I have a theory that this may be somehow related to changes made in newer NSUV on how UV sets are handled. I've noticed that there is a similar lag when you have some UVs selected and try to access the UV Sets menu in top toolbar of NSUV - you can try this with the same sphere as described above.

And one more issue to report. It happens in all recent versions of NSUV I've tried. The Unfold command accessed through the NSUV interface for some reason tooks much longer to perform compared to Unfold launched from the Maya's interface.

Steps to reproduce:

1) Create a sphere as above and select some of it's UVs.

2)  Hit the "Unfold the Selected UVs along U Only" button. There should be a lag of a few second before the operations finishes.

3) Try to perform the same operation through Maya's UI by selecting the Unfold command and executing it in Legacy mode with constraint set to Horizontal. It should happen almost instantly, with no noticeable lag.

Regards,
Sergey
