EasyVRayCameraAlongPath is a script for 3ds Max that automates building a camera move along a spline. You draw a spline, and the script links a new VRayCamera, path-constrains it to that spline, and handles the keyframing so the camera travels the length of the path.
The animation runs from 0 to 100 percent along the spline, with the tangents on that motion set to ease in and ease out. It handles these steps in one pass, which makes the setup much quicker than wiring the camera, constraint, and keys separately.
Written by colinsenner, EasyVRayCameraAlongPath is at version 1.0 and works with 3ds Max 9 and later. A demo video is available, and the developer's page at colinsenner.com has more of their work. This catalog lists the script as free.
