I have an up-and-coming robot that’s almost finished–my first project. His eyes are two spot lamps (with volumetric effects applied) coupled with two particle-emiting vertices to give it a lasery look.
After wrestling for quite a while I got the particle emitters to turn with the head. The particles trail behind the turn, which I would like to get rid of but could live with. The problem is that even with the head turned the particles end up shooting straight towards the z axis, at an angle to the newly-turned head. Even with recalculating–which at least gets them ending up emitting from the right place–they won’t end up shooting perpendicular to the particle-emitting plane.
I had to apply quite a bit of “z” force to get them to go in the right direction to begin with, so I figger that’s the culprit, but without it the emitted particles just go all over the place.
Thanks for any help!
