SCICRAFT Shader Pack — Complementary Reimagined (r5.4)
The modpack uses Iris Shaders (native NeoForge 1.21.1) as the shader loader. Download Complementary Reimagined r5.4 and drop it in this folder:
- Modrinth: https://modrinth.com/shader/complementary-reimagined
(installer button → "Download jar file", rename to
ComplementaryReimagined_r5.4.zip) - Mirrors: https://www.curseforge.com/minecraft/shaderpacks/complementary-reimagined
4GB VRAM / Performance presets
Open Iris: Esc → Options… → Shader Packs… → Complementary Reimagined → Shader Pack Settings.
Recommended for 4GB VRAM graphics cards:
| Setting | Recommended value |
|---|---|
| Preset | Fast (Performance mode) |
| Render Distance | 8 chunks (matches server view-distance) |
| Antialiasing | OFF |
| SSAO | Fast |
| Shadow Quality | 1.0x (0.5x for very weak GPUs) |
| Shadow Distance | 64 |
| Bloom | OFF or Low |
| Clouds | 2D Fast |
| Water Reflections | Screenspace Fast |
| Colored Light | OFF |
| Block Light / Entity Ambient | OFF |
Optional: enable "Vanilla Tweaks → Clear Glass" so Connected Glass mods remain visible through shaders.
Conflicts / Notes
- Iris & Oculus Flywheel Compat is bundled so Create's Flywheel renderer keeps working with shaders. If you see flywheel errors, toggle the compat mod's config or set Flywheel backend to "INSTANCING" in the Create config.
- Shaders are client-only. The server pack has no shader loader.
- If FPS drops hard, first lower Shadow Quality and disable Bloom before reducing render distance.
