Lesson learned, Crazy Bump cannot be trusted for everything.
Had been working on the siding tiles for one section of the house. Quickly found though that when Imported the diffuse texture into CB it was not exactly doing the effect I wanted, which meant it needed to be substituted for a texture that would give the desired effected of layered panels of roofing.
So began a few hours of tweaking around with that. which ended up leading to the following gradient map. . .
But Luckily I finally got the effect I wanted. Hopefully will be able to share that with you all sometimes soon. But its now early morning. . .
