Applying a texture useing the offset photoshop tool

When choosing a source file for texturing a 3D wall with a brick pattern, regularity is key. But I didn’t go that route with this texture. I wanted instead a texture full of irregularities, something that looked very weathered and very old. So I chose an image of a Roman wall to create a pattern of.  The biggest draw back is the actual history of the wall it’s self. The bottom of some Roman walls could be centuries older that the top, so there is an noticeable layering in the architecture.

This is not something you generally want in a texture pattern and by tweaking the saturation of the offset file I was able to minimize it at 1000px but at 2000 the layers become obvious and distracting. But again I chose a brick wall with layers built in the architecture as a sample for the fun and challenge of making it a seamless pattern.
