Venguard has released his Fractal remake, DM-FractalCore. He went through quite a few iterations and the final is a great version of Fractal for UT4. All of the Fractal goodness is there with excellent player visibility to boot. To read more about the making of this map, check out the forum thread HERE.
Will be putting this up on the UC Hub (when I get a chance to get custom content working…).
