We added support to resolve textures paths from FBX that are absolute to relative. This enables you to load textures with the file, without the need for manually reloading each texture.
For example, a problem texture path in the FBX file references C:\some_random_path\textures\blue\image.jpg; however, on your hard drive, the FBX file is at D:\my_path\test.fbx and the images are at D:\my_path\textures\blue\image.jpg. With 2023.2, this discrepancy can be resolved.
