It would be really useful for me, if it was possible to make a simple scale animation - either uniformly or along x, y or x only. The reference point would be the same you use for rotation animations.
I need it for things like deforming springs, gaskets, etc. And sometimes I would like to make objects appear or disappear through a combination of scaling and transparency change.
It is already possible to scale objects in Keyshot - you just cannot animate it.
