A utility for automatically creating RPF files for Map Mods. This will not work for vehicle mods (yet)
This tool uses PKG for NodeJS, so you will not need to install everything.
In the input folder, create a folder with the name you want your DLC Pack to have, for example MYDLCPack. This has to be unique as it'll be used as the DLC hashname etc.
In your newly created folder, place all the files you would normally place inside the replacement.rpf, such as .ymap, .ytyp, .ydr and so on.
Run index.exe to package your DLC Pack (You can create multiple folders and package multiple DLC Packs at once!)
In output you will find your folder with a dlc.rpf inside of it. The tool will have automatically generated all the files it needs, so you do not need to edit this rpf! :)
You can use these DLC Packs in RageMP 1.1 without affixing, or RageMP 0.3 with affixing via RageMp's plugin, or manually. These have not been tested with Base GTA V, but should be fine without affixing.
