ShowCameras
Made for hotkey use - if any cameras are visible - the script hides the cameras - if all cameras are hidden - it makes all cameras visible. Good for quickly hiding and unhiding all your scene cameras. Note: While there is a toggle under display to show or hide cameras - if you hide a cameras and then uncheck that box - the cameras is still not shown because you manually hid it. This script does not have that limitation.
For a max 5 - 4.2 version of this script - please download bspack_r4_r5_v031.zip. Use the original bspack_r42.zip if you want only max 4.2 compatibility.
The only major differences between script packages are slight version compatibility issues - there are no new scripts added between the 3 packages.
