I have a particle effect with a few sub emitters.
However, they are inconsistent.
In edit mode (not playing), particles and its subemitters appear properly.
In play mode, some sub particles are not created.
For instance, a gun fire would have smoke and some sparks. If I put smoke as the spark's sub emitter, every now and then, smoke particles fail to appear. (Sub Emitters' emissions set to burst, play on awake toggled, renderers on. Burst count is set to 1min, 1max.)
So after trying all sorts of fix, I found that QualitySettings->Other->V Sync Count interferes with sub emitters.
On "Don't Sync" option, fails a lot. On "Every V Blank" option, bit more than rare but noticeable. On "Every Second V Blank", I can't seem to find any case of failure (that I can see).
I have observed this behavior on 5.2.1, 5.3.6, 5.3.8.
Anyone know how to force sub emitters to generate properly without setting vsync options?
