share: maxscript > store camera resolution per camera
sublime tool
what:
simple maxscript that stores and reads per camera stored rendering resolution settings (width and height). You simply click on a camera of that list (list of your cameras in the scene) and it will change the aspect ratio of the safe frame and change your render width and height settings.
Its quite specific but perhaps its to some use to some people here.
I wrote this script yesterday from scratch for a current project in which I need consistent resolution density renderings for a high resolution comic (~ A1 in size).
here are a few screens:
some notes:
- early dirty code, works but could be refined and tweaked
- if you pick a camera from the list your current active view port will be set to that view with safeframe but not as camera but as a user perspective instead so you cant change the view by accident. The camera itself however will be selected as object
- the "...of A2" or "... of A4" are compared by the width of that size, not by the square size.
- "calculate" only fills in the pixel units for width and height in the textfields, it does not actually change the values of the camera.
