To Perspective

Align lights/cams...anything (Force, PFlow, FFD...etc...etc...) to current Perspective view.

99.99% you'd use it for a 3rd party light eg. Vray, Redshift, Arnold. I got annoyed at doing it manually so got into Frankenstein mode and cobbled together bits of codes here and there...so don't flame me for the lack of mxs expertise...

Just drag the ms file into viewport...

(of course, you can use it on Wind too...but as by default, when align axis is Z (for lights) it is 'flipped', so if you do use it on Wind, simply rotate it 180 degs after it's been aligned)

PS: I've tweaked so that it can align a group of lights, eg. a light tower at a sport stadium but I've found it's far simpler to link your group of lights/objects to a dummy, then align that dummy...this way you can repeatedly realign the dummy while if it was a group...it goes wonky after repeated align operations.
