I use Blender v2.77 and Cycles Render. I have searched for answers, but the solutions didn't help me with my issue. I have one object, which I can see always, but when I choose render as display method, it is gone.
Here are 2 screenshots. It concerns the "SpirulinaEmitter".
I am a total newbie with Blender, so it might be an easy error. but I am totally stuck right here.
Any advice is welcome.
