The modpack includes an Iris mod, which allows for the installation of shaders like Complementary Shaders, as seen in the gallery screenshots. While some mods, such as EnderIO and Mekanism, are noted to be in alpha stages, they are included and have been tested. Users are advised to create backups when updating the modpack. A comprehensive list of included mods ranges from utility-focused ones like "Nemo's Inventory Sorting" and "Refined Storage" to content-adding mods such as "The Aether" and "Industrial Foregoing."
