Particles rendering disapear sometimes according camera angle and position

Hi everyone.
I use Shuriken particles system to render a physical-based material simulation. It’s working (more or less !) until I found this pretty ennoying issue. With some point of view, according to camera angle and position, every particles dissapear. I cannot find how avoid it, (the scale trick to (1,1,1) doesn’t work) and nothing seems to improve this issue !
Has someone know a miracle trick to let the particles always visible, as long as the camera watch them of course.
THanks

You mean in the game or scene view? If in the scene view it might be because you have your camera in iso view. Change it to perspective and it might work, if that is ur problem

To be more specific : I use a cube mesh to render my particles (set in the inspector renderer panel - shuriken particles system -). There is no problem about the camera near or far plane, my particles are contained in the camera frustum. Both, the editor scene camera, and the game camera are ISO and suffer from the same issue : the particles dissapear according to the camera rotation and/or position.
Moreover, I create once all the particles in script and set them to the particles system. They are static since I want to render a volume, and have an infinite life.
Can someone help me please :slight_smile:

I found a way to make the mesh always render.
But you have to set particle system with LOOPING and PREWARM.
Prewarm will make your mesh always render.

Sorry for my english!

I tested this method in our game today, Prewarm doesn't work. But it works in my test scene... strange.. I found a new way to make the mesh particle always render, by adding a Birth sub-emitter, this should works. [16109-sub_em.jpg|16109]

Another way is setting Simulation Space to World. ![alt text][1] [1]: /storage/temp/16225-bdcam+2013-10-07+13-08-06-234.jpg
