How to get rid of EA's bump and specular maps

Quick noobie question, and I apologize if this is in the wrong thread.

I recolored an EA fireplace, and the inside of the original fireplace had small subway type tiles on it, I wanted to give it a more update and contemporary look so I replaced it with larger modern tiles. I also made sure to change the DST texture file for when it's lit.

When I put it in game and have my person light it, it shows EA's original bumps and outlines. So, I looked at the DTS files and saw where this seemed to be "embedded" into the gray DST file. I tried changing just that portion of it to a gray that matched, but didn't want to just wipe the entire texture out because it also had the "coals" as an embedded bump.

But, when I went back to the game to check, that didn't do anything.

So, would the files in this thread fix that problem or does that only apply to a cloned object? I was just doing a stand alone recolor.

Thanks for your help!
