This script is intended to replace the default Camera View (C) in 3ds Max with many cool functions.
A major upgrade from Smart Camera View 2. While still sharing the same idea as previous version, version 3 actually has been completely rewritten from scratch, based on a brand new algorithm and workflow, for speed and performance, with a lot of new features.
It will save you a lot of time when setting cameras, especially in scenes that has multiple cameras with different aspect ratios.
