hi @ all i am sure this sounds like a really newbie - question... (carrara 2) when i place a particle emitter in the scene, the particle emitter winsows opens. as far, as good. now I change the settings, for example duration, speed, angle, emitting range and all that stuff. I look to the preview, it looks like i would like it to look. i go back to the scene window and: there is nothing at all. just the emitter , and no particles. sometimes, there are a few particles when i scrubb the time once or twice, and sometimes there are some particles when i scale the emitter itself. sometimes when i do so, and do render later, it renders the animation, but only some particles appear, they dont move at all, some other appear, that dont move... i feel very sad about it. whats wrong there? do the emitters need different keyframes? and how should this work?and if so, why does the emiter window not display the changing during animation time? Absolutly desolated and thanksfull for every reply yours benjamino
