Hello thank you so much in advance, I have a problem with the particles, the particles are formed by GPU types, normal and Mesh. The particles disappear at some camera angles, but in editor mode they work great. I’m trying to simulate the rain, and through the event of the particles, I instantiate the splash effect mesh. But I’m experiencing the problem with the third-person character room. There are / there are settings that I should set. Sorry for my bad English. Thanks again. ---

Hi , When using GPU Particles make sure you have set the fixed bounds for your particle. If this is not set the moment the emitter is off screen it will stop rendering the particle. ![242253-setfixedbounds.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/9/5/2/95241d6c1b997324420aacd19743ae6f8d93a6a3.png) ---

Hi , thanks. I have already tried many times to fix the bounds, but unfortunately the result is always the same. I’m going crazy xD. ---

another thing, the particles that generate splash spawns have no Type data and the splashes are of the mesh type [Screenshot](https://gyazo.com/977c94302fe1f25a0ccf0442260d3b38) ---

I see. Then just set the bounding box manually to something huge like 500.000, by clicking the empty space from the emitter list, and scrolling down to “Bounds” like in this screenshot: [https://i.imgur.com/9eY155B.jpg](https://i.imgur.com/9eY155B.jpg) ---

same problem here, particles are visible at some angle, turning the camera l/r or up, make the particles disappear ---

I had the same issue with a particle made of multiple emitters, one of which was a GPU Particle, and **even if off** it was still giving me the issue of disappearing at certain camera angles. To solve it, as said above, when using GPU Particles make sure you have set the fixed bounds for that particular emitter. Click on “Bounds” icon on the top toolbar, then “Set Fixed Bounds”. This fixed it for me. ---

I think have to be something related to collisions. Disabling them fix the problem but is not what I need. ---

On the detail panel for your particle emitter, check the box for ‘allow recycling’. that worked for me ---

If you’re working with Niagara look for the options in your Niagara emitter when you place it in your scene and look for ‘‘Bounds Scale’’. It fixed it for me. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/e/1/4/e145bda843af2d08b3650b329f3a6be3959d40ab.png) ---
