Long time reader, first-time poster. I’ve been working on a model of an EMD Locomotive for some time now and I have not been able to find a solution for recreating this warped/bent metal look that a lot of the panels seem to have on locomotive and railcars. Any suggestions or thoughts?
If you look at the specular and reflective highlights you can see contours showing that the metal panel/shell of the locomotive is not completely flat but instead warped/bowed outwards in somewhat random places.
I’ve tried using a cloud texture with a displacement modifier but the effect doesn’t seem to match what we see here. I’m almost wondering if maybe I should make use of vertex painting so that parts of the locomotive that would have structural support behind the panels would not be affected by the displacement modifier… Any and all suggestions would be truly appreciated!
