Hi
This is a simple python script, which create independent copy of selected
camera. All dependencies, parenting, targets etc. are resolved and recalculated
to "standalone" Nuke Camera, with baked XYZ. Such a camera You can export with
chan file or fbx or whatever.

wouldnt it be epic if every 3d node had their world space coords easily

Anyone know of a way to export (or even get the position of) a camera which is
parented to an axis?
I'm using Nuke 7 and trying to get the camera to Maya 2013.
I've tried exporting fbx and Alembic as well as some scripts from Nukepedia but
nothing seems to work.
I can see looking at the world matrix the xyz positions of the camera but can't
get the rotation values.
Any suggestions greatly appreciated
To Nuke or not to Nuke
