How can I rotate object relative to it's local axis? I found a blender 3d model that I would like to use in the game I'm making, however, it's front is at 45' angle relative to it's local axis (see the attached picture). The game engine I'm using (Unity) is using the local axis to determine the front of the object when moving it and as a result the ship "drifts sideways" instead of moving forward.
Is it possible to rotate all the meshes of the ship relative to their local axis?
Applying the rotation will solve this issue.

Shortcut: CTRL + A

This will make the rotation to be equivalent to 0 degrees in each plane.
The selection will not be rotated, the current rotation will be considered to be the default rotation.
