I have a plane that i have scaled to be the exact dimensions i need for a sprite. All is good and then i need to rotate it. I want 3 objects to each have random rotations around their y. When i rotate it manually using the rotate tool i have a problem. The plane stretches and becomes a parallelogram and not a square anymore. This is a problem because the texture distorts with it. How should I manually rotate my plane to avoid the distortion of the plane?
This is a known problem: non uniform scales (different values for each axis) cause this distortion when the object is rotated. A good solution is to child the scaled plane to an empty game object, and apply the rotation to this empty object - the plane will follow the parent rotation without any distortion.
