That fixed it! I changed my resources.cfg so that only /assets is listed (as opposed to all of its subdirectories) and copied the resources.cfg file to my config folder.
Also, I had linked a lot of meshes to a folder I made in SOMA's original static_objects folder (before I knew what I was doing), and since this isn't what I wanted, I copied all my custom meshes to within the mod folder's static_objects folder. And this managed to resolve the file paths of the meshes linked outside the mod folder to those linked within it. Thanks again --Cade
