I love driving formula cars in AC (particularly RSS Hybrid) but like to have the right tire colours on for the compound I'm using for that extra immersion. I've found this to be a bit of a pain, as if you want to do all the skins at once (e.g. for a race), it involves a lot of manual copying of files.
I've made this windows application to put an end to that. It will allow you create multiple presets, consisting of a source tire textures (pack) folder, and a destination car skins folder. The program will then copy the files from the selected tire colour folder to all of the skins inside the car skins folder at once saving lots of time and effort.
So far I've used this with RSS Formula Hybrid 2017 (& S1) and the RSS Formula 2. It could also work for any other cars that have a similar idea of various tire texture options.
You can save up to 30 presets.
More detailed instructions are included in the PDF readme in the zip file.
I developed this for my own needs but thought I'd share as it may save others some time also. As such I don't plan on doing any updates, as I think it's good enough for my own purposes. If anyone finds any major bugs then I am happy to have a look at them.
Disclaimer: This application has been developed as a Windows 10 desktop application (using the free Visual Studio 2017 community edition). I have heard it works on Windows 7 but can't guarantee as I haven't tested it on anything but my own Windows 10 PC myself.
