Voronoi and geometry

[VictorGamma]

Hello, I am having this (see image) issue while using Voronoi Fracture, the mesh looks good in the viewport however while rendering, it looks like bee-hive.  I have tried flipping the normals, resetting xform, shell, attaching the model to a new mesh.  
Note:- When I use Voronoi on a regular box it works fine but not on this mesh.  Just curious if anyone has any suggestions or ideas? 

Thank you in advance!
