3D models often come with associated image files like texture maps or normal maps. When exporting an FBX with external textures, the FBX file contains information about the location of the specific texture files linked to the material. If these texture maps are stored in a random folder during export, after importing the FBX in RoadRunner, the model may not be able to locate the textures, as it expects the files to be in the same location as the random folder. I suggest using a software like Blender to ensure the texture paths are in the same folder as the model before exporting it in FBX format.
In the RoadRunner Asset Library, try placing the texture and normal map files in the same directory as the model. Alternatively, using an FBX model with embedded textures can also be a viable solution.
