| Fresh Animations 1.10.4 |

| Complementary Reimagined r5.8.1 |
Shaderpack (Euphoria-patched, included) |
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 = true for 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 the indirect backend.
