Can the orientation of objects emitted from a particle system be controlled? When emitting objects from a particle system (boids) the objects appear with random orientation, while they move it would look much nicer if e.g. a spacecrafts nose would point into flight direction.

It seems to have a leader at the first position of the Boids Brain panel helps but then the particle tend to clump, when separation is added they start to move with random orientation.
The mesh should be rotated in Edit Mode so that the nose points into the emitting direction, then the will always point to the flight direction. 



The rules to prevent clumping:
