Very noisy scene

Hi,

I’m quite new in Blender (and in 3D modeling too) and sometimes when I find a problem it’s hard to search for a solution because I don’t know what to search. So, I know this is probably not a big issue but can’t find the solution.

I attach an image of the render, where you can see that most of the objects have that black noise all around (especially the tubes on the left and the beginning of the big one. Any idea of what can be causing it? Thanks for the help!

Hi, switch AO off, and give Lamp higher samples.
Try 12 or higher.
Your tubes have many double vertices/faces, remove them with key W remove doubles.

Cheers, mib.
