Key mover is a script for keyframe's manipulation in 3ds max on one or more animated 3D objects at the same time. You can also perform key`s time and values randomization on multiple objects at once.
Key mover is a script for keyframe's manipulation in 3ds max on one or more animated 3D objects at the same time. It is primarily designed to move the keyframe's 3d objects that are animated together. so you do not animate or move keyframes one by one, you can do it easily with the Key Mover script.
Beside of this you can perform key`s randomization (moving keys randomly or shifting the key`s values - a position in 3D space, rotation, or size of the 3D object) and increase or decrease the spacing between the keys, without having to open the Curve editor panel.
Tip:Key Mover sort object selection by name(asc) and using that order move keys one by one.
