The Rotation Tool was made to enable the user to rotate multiple objects in selection. This proved to be very useful since you can get variation in just one prop by rotating it. Then artists doesn’t have to produce multiple kinds of trees for example and they can focus on props that gives more “bang for the buck” making levels even more interesting and leveldesigners lifes a bit easier.
As you can see in the window all the user needs to do is to type
in which axis and how much the selected object(s) should be rotated.
By unchecking the checkboxes to the right the user could lock which
axis should be rotated and which shouldn’t.
