Fabian:
I think that you could somehow force Nuke Studio to do so, but we also need
it for the artists as they don't want to do foldercreation them selves. I
know they are working on a solution to this problem, we just don't know
when its ready.
Erwan:
The code can be condensed yes, but it is written for our demands (like the
tag check)
The reason why it uses a subprocess is that Nuke Studio doesnt seem to be
able to execude code inside a external nuke project file. Using the
subprocess i can launch a window-less version of Nuke and execute any code
in there within a millisecond. If you had to do that with a windowed nuke
it would take ages.
