So I am trying to achieve a decent looking storm cloud effect. I think what I have right now looks pretty good, at least in the editor. When i run on my Gear VR the particles "pivot" when you turn your head in a wierd way that makes the whole ting look woonky. I have read that this is a problem with particle effects and VR but i haven found that much about what the cause of the problem is or how to create a good smoke/cloud effect in unity that is suitable for VR. Any input, tips or simple explanations on the subject would be appreciated.

    Not sure what you mean in regards to particles. Smoke, sparks, fire...all pretty cool in VR.

    So what's happening is that the particles are billboards, and they're rotating to face the camera.  I sadly do not have my project handy at the moment where I am, but you want to set the view they face so it doesn't do that wonkiness you're talking about.  It's really simple, if you look at the renderer of the particle system, there's a thing there you want to change. 

    Sorry for the vagueness, literally going on the memory of what it is as this is something I had to do about a month ago.  Seriously though, very simple once you change that one thing, will probably fix your issue.

    See https://docs.unity3d.com/Manual/PartSysRendererModule.html.

    You want to change the render mode to Mesh, and make sure you've provided a 3d mesh to use for the particles. Also be sure to turn off cast/receive shadows, as that will seriously affect performance. The other billboard options might also work, depending on whether your camera can change position. Experiment with the options and see what works best.
