Hello,
Sorry for stating the obvious in my previous post 🙂
Indeed, in Editor the Sample Particles System clip does not take into account World Space and I dont think that is possible with the ParticleSystem API, but in play mode the particles play fine is that correct? (it does here).
The editor simulation is really meant as a preview.
We can change the action clip to simply play/stop the particles instead of simulating them explicitely, but the downside of this is that the particles will not respect the current time the we are in the cutscene.
To test what I mean out, you can open up SampleParticleSystem.cs and completely comment out or delete the OnUpdate function in there.
Let me know if after doing the above, you prefer the results over how they are now, but once again, please remember that the simulation taking place in editor is a preview. What is really important of course would be the particles to play correctly in play mode 🙂
