Shuriken "Distance" emission mode not working

Archived Forums Questions & Answers

My particle system works as expected in Time emission mode, but I need it to emit X particles per unit traveled. I’d almost swear I’ve successfully used Distance mode before, but right now when I change from Time to Distance it simple stops emitting particles (yes, I am moving the object).

Shouldn’t 5000 distance mean “Emit 5000 particles per one unit moved”? What’s going on?

Here’s a picture of my system setup - default settings with Distance instead of Time. :confused:

I'm not quite sure. I am not at home right now. But I thought distance was distance traveled before something was emitted. Anyway, there is a great tutorial on the Shuriken particle system in the live training archives. http://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/particle-systems

The video talks about distance mode but does not show it working. (~26:45)

Crap. I thought he went through each parameter thoroughly.

No worries - as you can see, the answer is a little not-straightforward. x)

You must simulate particles in World space to use distance mode. Simulating in Local space does not work.
