Power Box Texture

Here is some steps to the how I created the texture that I will put on my Power Box ( The Right One). I kept the same process I had in the test, but made sure the rust didnt totally cover the Uv map because I didnt want rust all over the model. Also This time I remembered to remove the actual map so it would show on the model. When it came to creating the bump, I used the colour itself rather adding a image, I used the desaturate, curves and high pass to this as well. What I realised is, as I had a lot of variation in colour and opacity in the brush, photoshop could create a large difference when high pass was added.... time to add it to the model....
