It won’t show me particle simulating. while in scene mode(scene editing)
it works in game.
If game is running and I switch to scene mode it will show.
But In scene mode.
There is no playback time passing when I press simulate.
I use
Unity 5.4.3xEditorVR-p3 (64-bit)
IT updated every old version projects.
I’m having the same issue (Unity 5.5.1f1).
I can manually move the particles forward or backwards changing the “Playback Time” on the Particle Effect panel in the lower right corner of the viewport, but pressing Simulate does nothing.
Update
I don’t know if this helps or not, but I’ve got my Simulate functionality back. While the scene was running I selected the particle system and noticed that the same Simulate / Stop buttons popped up. I clicked simulate and it worked like it should. When I went back to the editor, Simulate started working properly again.
