I want the sparse cracks function to inverse, white cracks on the black background. 

How do I do that?  I tried to "inverse" in the FE but that didn't help, I also tried to multiply by -1 didn't help either..

Anyone?

Simple, just switch positions of your material.

Simpler: change your "invert" node for an opposite filter node. Invert is a math node that will invert the input number only

Very simple Bruno's way, too!!!
