Voronoi Fracture material different in render

[stevenmenegozzi]

I'm having difficulty with the material projection using a Voronoi Fracture object. I've tried every type of projection and none of them match the render in Octane. I'm not even sure how Octane is creating the look of the material, as it looks nothing like what it should. In the attached screen shot, it should look like the column on the right, which looks like concrete. In previz, the columns in the Voronoi Fracture look how they should. Thanks for any help!

Better to make a new test scene with an object and similar setup from scratch. So you can find what's wrong!
