Particles set to Horizontal Billboard reappear when they should be off screen

Unity Engine
1

I have some particles set to Horizontal Billboard to act as a ground fog effect. They work well and I like the effect, but if my character walks away from them and they leave the screen, they start to reappear again and fill the screen until I move a little further and they suddenly disappear.

If I switch them to just Billboard they work fine, but I have big particles and Billboard rotates them so they clip through the floor.

I just made a example project and sent a bug report to unity, but I was wondering if anyone else had seen this problem and knows of a work around?

I did eventually find a work around for this, at least in my case. I forgot about this tread or else I would have updated it.

When I first created the particles, in the Renderer tab there is a setting called Max Particle Size which defaulted to 10 (or perhaps I messed with it, either way, it was 10). I eventually found that changing that to 0.8 fixed my problems. I didn’t think of that at first as 10 seemed like a nice large size, but the value is really in screen space, 1 being the whole screen.

Hopefully this will fix your problem too.
