I am used to editing prop surfaces. Usually there is an image file. Change the image file in photoshop, re apply, boom. Done.

However I am running in to problems with a particular prop object. This is where I got it from: https://www.deviantart.com/mdbruffy/art/TMP-Era-Shuttlecraft-392410293 I would like to be able to alter the numbering and lettering graphics on the shuttle exterior. However none of the texture files in the texture folder seems to contain the lettering of the ship name, shuttle number, etc. Nor is the map accessible through "surfaces" in Daz. Where are these graphics hidden and how do I modify them?
