Additive

Additive bundles dozens of rendering, lighting and interface mods for Fabric into one modpack designed to replace OptiFine feature for feature. SkywardMC keeps it synced with a lighter sibling called Adrenaline, and Additive runs on the client only, since no supported server-side build is offered.

What Additive replaces

Rather than one closed mod, Additive leans on a stack of open, source-available alternatives. Every mod in the pack stays individually swappable if a reader wants to strip one out.

What's included

• Rendering and shader support through Sodium and Iris Shaders, plus better grass and snow
• OptiFine and custom capes support
• Dynamic lighting from held items and an integrated zoom feature
• Small input fixes for macOS and Linux players, plus a free LAN world hosting feature
• Borderless windowed play as a video option

Installing Additive

Because this ships through Modrinth, the usual route is a launcher that reads Modrinth packs, covered in how to install a modpack; Fabric itself needs setting up first, which this guide walks through. SkywardMC also offers its own standalone setup tool directly from its site.

The newest release folds its dependencies in directly and needs nothing extra, but a few older releases for 1.16.5, 1.17.1 and 1.18.2 each pull in a long separate list of rendering, texture and lighting mods instead. Its Quilt track has gone quiet, leaving Fabric as the only actively updated route into the pack.
