How do i make cracked dirt

Hey i'm doing a 3D project in cinema 4D which will be a gun showdown with a saloon in the background and a wildwest setting, I'm trying to make a "cracked dirt" texture for the floor and can't figure out how to do it, does anyone have any tutorials or any ideas how i could make a cracked dirt repeatable texture in cinema 4d or even photoshop and then import to C4D?

a sample of the idea i have in mind



Kind regards,
David Lambert
