This is a WIP mod that allows for the repair of individual parts. It adds a UI app called "Individual Part Repair Menu" that can be used to select individual parts for repair, and enabling the "deep" option repairs all nested parts. I started making this mod a while ago, but ran into problems when the new dynamic door system was added to more vehicles. This is mostly because the way parts are repaired is very similar to the current in game beamstate save/load system, which is also currently bugged as when loading a beamstate the new doors will not work and be stuck open. I recently picked it up again and found that the solution is to load the beamstate during the a vehicle reset, which seems to resolve the problem completely. This current version is pretty bare bones, mainly a menu showing all parts with a button to repair them and also an option for repairing nested parts at the same time. I am working on a newer version with more features like better menus and the ability to search parts by name that can be accessed early on my Patreon.
It ended up working way better than I thought it would too, it could be added to career but due to the current save/load system it would break when you change parts on the car. I am currently rewriting it to save and load damage more dynamically so that parts can be added/removed without affecting the rest of the car, but it seems to be a bit more problematic.
