StereoCraft: Stereoscopic 3D

Consistency release: the same feature set on every supported version, now including Fabric 26.2 and 26.3, and stereo correctness checked by automated tests on all six builds — vanilla, with shaders, with Distant Horizons and with Voxy.

New

• SBS_FULL mode (issue #4): full-resolution side-by-side, each eye at the normal aspect ratio, alongside SBS_HALF.
• Fabric 26.3 and Fabric 26.2 builds.

Fixes

• Entities and particles popping out more than the world (issue #5). Several causes, all fixed:
  • With Sodium 0.9 (26.1.2, 26.2, 26.3), terrain lost the convergence shift while entities kept it.
  • Distant Horizons terrain was drawn without eye separation, flattening the distant landscape onto the convergence plane (26.x).
  • Particles were drawn without eye separation (26.x).
• Swap eyes did nothing visible (all versions since 0.1.2). It now swaps.
• Distant Horizons: the left eye could show a stretched full-width image (26.x).
• Voxy with shaders (TAA): Voxy terrain was reprojected from the wrong eye (26.1.2, 1.21.11; same fix on 26.2/26.3).
• Vanilla world could stay invisible after switching stereo mode with Distant Horizons loaded, until the camera moved (26.2, 26.3).
• 1.21.11: stereo depth was inverted (each eye rendered from the other side).
• NeoForge: no stereo depth (the eye offset was overwritten every frame).
• Angelica/GTNH: achievement/tutorial popup shown in one eye only.
• Plus per-eye panorama, shader render-target and SBS_FULL GUI/cursor parity fixes across loaders.

Compatibility changes

• Fabric 26.1.2 now requires Sodium 0.9 and Iris 1.11 (current versions; Distant Horizons 3.3 and Voxy 0.2.18 need them too).
• Fabric 26.2 requires Fabric Loader 0.19.5+.

Tested with

Known upstream issue: on 26.2, Voxy 0.2.19 draws no terrain under Complementary Reimagined r5.9.3 even without stereo.
