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 a live instance located at ~/.local/share/PrismLauncher/instances/Create Aeronautics - Airship & Expansion/.minecraft. Set MODS_DIR / 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.
