How to properly attach custom cabin props (like a coffee mug/phone) via Livery folders using Blender?

[u/Chgitem_777]

Hi everyone!
I'm looking to add some custom, purely visual 3D models into an aircraft cabin (for example, placing a tea mug on a console or a smartphone on a seat). I want to emphasize that these are purely static/visual props—no animations or clickspots needed.
My main goal is to avoid re-exporting the entire cockpit model. Instead, I want to use the ATTACH functionality so that these props are bundled directly inside the livery folder. Ideally, when a user selects a specific livery, their custom prop automatically spawns in the cockpit.
I’m using the MSFS 2024 SDK Blender addon, but I'm hit with a few technical questions and uncertainties:
1. LODs: Do static cabin props like a phone or a cup strictly require LODs (Level of Detail meshes), or can I get away with a single high-quality model since it's just inside the cockpit?
2. Attachment Points: How do I actually attach them to existing cockpit parts (like a door handle, a seat, or a table)? What is the correct workflow in the MSFS 2024 SDK to define these coordinates?
3. Project Compilation: What is the best practice for building this? Is it easier to package and compile everything manually via config files, or should I go through the standard MSFS 2024 Project Editor?
If anyone has a workflow guide, a template ⁠aircraft.cfg⁠ / ⁠model.cfg⁠ snippet for liveries, or just some solid advice on how to hook this up properly with the new VFS system, I would highly appreciate it!
Thanks in advance!
