Particle Alignment

Hey guys,

I’m using particle systems with Dupli Groups to build convincing looking walls and roofs. Emitter objects serve as invisible skeletons that are set to emit one particle per face/quad.

As long as the emitter object’s geometry is simple i.e. mostly perpendicular, everything is fine and dandy. What I’m struggling with, are more organic shapes where particles suddenly no longer follow the quads’ alignment.

Any ideas on how to fix that?
