nullptr’s Valhalla

Valhalla is a vanilla-plus modpack built for Fabric on Minecraft 26.1.2. It’s designed for players who want the familiar vanilla survival loop, but smoother, prettier, and better optimized — not a tech or magic overhaul. Every mod below is included specifically to refine the base game rather than replace it.

Visual Enhancements

• Tachyon — a custom shaderpack (included in the modpack) providing enhanced lighting, shadows, and atmosphere rendering, built specifically for Valhalla.
• Iris Shaders — the shader loader that runs Tachyon and other Iris-compatible shaderpacks on Fabric.
• Voxy — a Level of Detail (LOD) mod that renders distant terrain at reduced detail, dramatically extending visible render distance without the normal performance cost.
• Falling Leaves — adds falling leaf and flower petal particles beneath trees for a more lively overworld.

Audio

• Sound Physics Remastered — adds realistic sound propagation: sounds echo in caves, muffle through walls, and reflect off surfaces based on the surrounding geometry.
• Atmosfera — adds ambient environmental sounds (wind, birdsong, cave ambience) to reinforce the atmosphere of each biome and location.
• Plasmo Voice — adds proximity-based voice chat for in-game communication on the Valhalla server.

Performance & Optimization

• Sodium — a rendering engine replacement that significantly improves frame rates and graphics performance.
• Lithium — a general-purpose game-logic optimization mod that speeds up tick processing without changing gameplay.
• FerriteCore — reduces memory usage, helping the game run more smoothly on lower-end systems.
• Entity Culling — skips rendering entities that are behind walls or otherwise not visible to the player, improving performance in dense areas.
• VoxyServer — allows the server to upload LoD data to the client.

Quality of Life

• Zoomify — adds a configurable zoom keybind for a closer look at distant objects, similar to OptiFine’s zoom.
• Mouse Tweaks — improves inventory mouse interactions, including drag-filling and scroll-to-move item behaviors.
• Mod Menu — adds an in-game menu for browsing and configuring installed mods directly from the title or pause screen.

Compatibility

• Mod Loader: Fabric
• Minecraft Version: 26.1.2

Server-Side Content (Valhalla Server)

The mods above are everything included in this modpack download. The Valhalla server additionally runs the following datapacks server-side — these require no extra download or client-side installation, but shape what you’ll encounter while playing:

• Ragnarok (custom) — a custom Overworld terrain generation datapack created for Valhalla, inspired by JJThunder’s terrain generation work, reshaping overworld landscapes with new terrain shapes and variation.
• Incendium by Starmute / Stardust Labs — overhauls the Nether with 8 new biomes, jigsaw-generated structures, custom mobs, weapons, and loot.
• Stellarity by kohara_ — overhauls The End with new biomes, reworked End Cities and Strongholds, a revamped Ender Dragon fight, and new items and crafting mechanics.
• Vanilla Refresh by Splatus — a 30+ feature quality-of-life datapack adding small conveniences like player sitting, equippable banners, a day counter, and improved spectator mode, while staying true to vanilla feel.
