bmwcarit/digital-car-3d ? reverse-engineered prompt

Help me turn this repository into a clean, polished digital 3D asset package for the BMW X5 2018 model.

I want someone landing here to immediately understand what the model is, how to use it, and how to preview it with the Ramses 3D toolchain. Please improve the project so it feels ready for public release, especially the G05 BMW X5 files and the README. Make the instructions simple and friendly, and add anything small that would help a person open or inspect the asset locally if that is missing.

If there are any obvious gaps in the docs or structure, fill them in with the minimum sensible setup, but keep the focus on this one vehicle model and the idea of digital 3D assets for BMW vehicles. Look up current Ramses docs online if you need to.
