# Rendered image only black and white noise

I am new to Blender and try to reproduce a YouTube TutorialBlender Tutorial: Splash Effect. Everything works fine, up until I try to render the image. What I get then is nothing but black and white noise, also known as salt-and-pepper noise:

I re-checked that the three light sources are set to Emission. The number of render samples is set to 10, but also increasing it to 100 doesn't change anything.

Here is the blend file

I'm sure I made a stupid noob mistake, but which? Thanks a lot, Polis

• The best way to get help is by posting your blend file. – user1853 May 8 '15 at 17:10
• I'm surprised that people can't answer that question right away as it appears to be quite a noob problem. Anyway, I added a link to the blend file now. I hope you can open it. – Dietmar Haba May 11 '15 at 8:16
• You have two fluid domain objects. Try deleting one of them. – gandalf3 May 11 '15 at 8:36
• I just deleted the outer fluid domain object and now everything seems to work. However, I don't understand it as I think I did what was explained in the video, and it works there, and also the simulation worked fine. But thanks anyway. – Dietmar Haba May 11 '15 at 10:56

It appears you have two fluid domain objects, one of which has no material (Cube).
