Is it possible to keep particles orientation relative to the emitter when the emitter is rotated? I have a plane with a particle system with display type Group. Is it possible to keep particles oriented along plane (1st pic) when I rotate the plane? I'm getting particles as in 2nd picture and that's not what I want.



And this is what I want to get after rotating
You have to check Rotation, to make the particle system uses the dupli object's rotation. Using this setting, particle orientation can be tweaked by rotating the dupli object itself:



Next, give one of the object's local axis as the particle system's initial rotation. This way, any new particle will be oriented to that axis:



Now any new emitted particle will always be correctly oriented:
