Proxima Vis: Integration is the coremod for integrating the various mods in the Proxima Vis modpack. It allows Gregtech to integrate materially with the various features of other mods. It includes compatibilities with Botania, ExtraBotany: Reburned, Applied Energistics 2, and Proxima Vis: Core.
Theoretically the mod can be used with just its dependencies and not inside the intended modpack but this is not recommended. Do not report bugs if using the mod outside of the Proxima Vis modpack.
