title: Fatal error! System out of memory! UNITY 3D
body: <p><strong>I was working in a scene with only some 2d spirtes and recently added a Particle System with one sub emitter with a collision effect. After working and testing it for a few min I always get this fatal error. I don't know why I get this.
  My laptop has 16gb of RAM.
  Unity version 5.4.1f1 64bits</strong></p>
