Is it possible to hide particle emitters in the viewport without hiding particles? Is it possible to hide a particle emitter object in the 3D view while keeping particles visible?
I know you can do this in the render with the Render Emitter setting, but this does not affect the viewport.

Sometimes the emitter can get in the way, though it's still useful to know where it is. The ideal solution then is to make it drawn as a wireframe, but setting the Maximum draw type to Wire or Bounds causes all the particles to be rendered as wireframes or bounding boxes too.

Setting the emitter object's draw type would work, except it also changes the way the particles for that emitter are drawn:

 

Is there anyway to make particle emitters hidden or less distracting while keeping the actual particles unaffected (still rendered as solid or textured)?
Another way (similar to Michal's answer) is to use a Mask modifier:

Add an empty vertex group to the particle emitter by pressing the + button in Object Data &gt; Vertex Groups:



Add a mask modifier after the particle system with the empty vertex group:



There was a bug in 2.69; in order for the mask modifier to work you had to assign and remove some geometry to the vertex group. It has since been fixed.
