A modern port of the classic fabric Origins mod. Backwards compatible with most of your favorite origins expansions. Just drop them in the origins packs folder in the config folder of your modpack and they will be imported in.
Not every old origin pack will work 100% of the time, let me know,ideally on my discord, which one your having issues with and I will attempt to fix this.
