Particle system doesn't seem when the target is so close. Please help.

As i said in the topic my particle system working well but doesn’t seem ‘‘when the target is so close’’, even if i make the box collider really smaller but still the same problem continues.

Thank you for your help, have a nice day all!!

I am not sure if this is your question, but if you’re too close with your main camera to any object it disappears. That is due to the camera having clipping planes, you can set the near value low, to like 0.01.
