The Wide Ratio Camera Tool creates a camera rig that overrides the project's image output ratio.
- The final output image is for tv (HDTV 1280x720) : ratio 1.77.
- We want to display some 2.35 ratio for a "movie effect".
It works with 3dsmax's default cameras (free and target), and VrayPhysicalCameras.
The ratio is handled by a Custom Attribute in the created "c" helper.
The masks are properly wired : the ratio and the camera's focal length can be animated.
