Reaper's Sky
A curated Minecraft modpack about airships, exploration, and tech progression. Minecraft 1.21.1 / NeoForge 21.1.248 — 107 mods.
Install (Prism Launcher) — one link
If you don't have it yet, grab the latest Prism Launcher here: Prism Launcher download
- Open Prism Launcher → Add Instance → Import from ZIP.
- Paste the raw URL to the
.mrpackfile in this repository (e.g.https://git.reaperofveriod.nl/ReaperOfVeriod/Reaper-s-Sky/raw/branch/main/ReapersSky-1.2.0.mrpack). - Import. Prism downloads all mods, applies configs/shaders/resource pack, and sets the instance up automatically.
- (First launch) Allocate 8 GB RAM in Settings → Java → Memory. Requires Java 21.
- The multiplayer server
reaperofveriod.nlis pre-listed — just hit Multiplayer and join.
Server install (Debian 13) — one link
Run this on the server box (sudo/root; needs internet). It installs Java 21,
NeoForge 21.1.248, all 90 server-side mods (sha1-verified), and writes
eula.txt + server.properties + an 8 GB run.sh:
curl -sSL https://git.reaperofveriod.nl/ReaperOfVeriod/Reaper-s-Sky/raw/branch/main/server/install.sh | sh
Then start it (keep it running with tmux/screen):
tmux new -s mc
cd ~/reaper-sky-server && ./run.sh
The world generates on first boot — wait for Done (...) and join at
reaperofveriod.nl. Full details in server/README.md.
Updating the server's mods (maintainers)
After adding/removing mods in the Prism instance Reaper's Sky - dev, push
them to the live server with one command from the repo root:
python3 server/build_mods.py --push
It regenerates server/mods.json, uploads it, then on the server:
stop → sync mods (prune stale + download new, sha1-verified) → start, and
waits until the log shows Done (...). No git commit needed first. See
server/README.md for details,
manual options and troubleshooting.

|---|---|

Key config already applied
- Flywheel backend forced to
flywheel:indirect— fixes the Create throttle-lever "ghost image" artifact under Iris shaders. - aero-shadow-fix bundled — fixes the white balloon ghost.
- Iris is preset to load the included Complementary Reimagined shaderpack.
irisflw replaceCheckerboardTexture = truefor correct textures under shaders.
After import
- Enable Fresh Animations in Options → Resource Packs (ships alongside 3D Skin Layers).
- If shaders look off, verify the Complementary pack is active in Options → Video Settings → Shader Packs.
Rebuilding the pack (maintainers)
python3 build_mrpack.py regenerates the .mrpack from the dedicated
"Reaper's Sky - dev" instance at
~/.local/share/PrismLauncher/instances/Reaper's Sky - dev/.minecraft.
Set INSTANCE (and OVERRIDES) at the top of the script to point at a different
instance.
Known limitations
- Create Aeronautics has known visual issues under Iris; the bundled config/mods resolve the most visible ones (balloon + throttle lever). Occasional artifacts on animated Create instances may still appear.
- Shader uniform warnings in the log (
_flw_cullData,flw_frustumPlanes) from Veil are cosmetic and do not affect rendering on theindirectbackend.
