RandomizatorRT is a small script that eases the everyday randomization needs of artists by making the changes appear real time on the viewport - just enter the desired values or spin some spinners to see the randomization happen right away!
The expandable UI allows for quick and fast randomizations or more complex, value constrained, selectable axis randomizations in Expert Mode.
The script is still in alpha, but it's fully functional and will not (hopefully) break your scene or mess with your animations if you happen to be randomizing animated objects.
