I don't know had happened, down there you can see the emitter, I did an instancer replacement and you can see that pop-corn just drop from above, how ¿? don't know, did this on a clean file and it works.
Steps->Create Emmitter (NParticles) >Create Instance..... and then this happens,why?
So .... I managed to import the PopCorn as an Obj. this is what MAYA said....
I think it had something to do with that but I just picked up a different corn mesh and just did the instance, I thought everything was gonna be alright but now this happens, I set a passive collider on the head of my character, I changed self collide, collide, I switched collide thickness of the passive collider...but the PopCorn just does nothing, as if these values had no influence on them....what do you think?
