Opal Shaders 1.0.0-alpha.8

Alpha release. Back up your worlds and report problems with your logs/latest.log.

Supported: Fabric 1.21.1, 1.21.10, 26.1-26.1.2, 26.2, 26.3 · NeoForge 1.21.1, 26.1-26.1.2, 26.2, 26.3 · Forge 1.21.1

New

• Colored lighting and voxel compute on Minecraft 1.21.1, on Fabric, NeoForge and Forge (OpenGL).
• Colored lighting on Vulkan for Minecraft 26.3. Packs that use compute shaders and storage buffers now start on Vulkan instead of falling back to vanilla.
• NeoForge ports for Minecraft 26.1-26.1.2, 26.2 and 26.3.
• Particles now use the shader pack's own program on 26.2 and 26.3, so glowing particles such as Nether portal particles look as the pack intended. On 26.1.x, particles are still drawn by the game.

Fixed

• Nether and End rendered with Overworld shaders on 26.x and 1.21.10. Packs now load world-1 and world1 programs per dimension, which fixes grey fog and wrong lava in the Nether. The pack reloads when you change dimension, so expect a short pause at portals.
• Glowing Portal Edges now works on Vulkan on 26.3, since it depends on colored lighting.
• A failed pack load on Vulkan could crash the game with a lost device error.
• A raw opal.screen.chainFailed text was shown in the shader pack screen.
• Raw key.category names in the Controls screen on 26.x.
• The NeoForge deprecated logoFile warning on 26.x.

Known issues

• Colored lighting on Vulkan works only on 26.3. On 26.2, select OpenGL or turn colored lighting off, on 26.1.x and 1.21.x use OpenGL.
• Distant Horizons is not supported: its distant terrain does not appear with Opal and it lowers FPS.
• Some players report shadows and water moving while walking (seen on NeoForge 26.2). Under investigation.
• Some players report black, broken terrain on mountains with several packs. Under investigation.
• Abyss on 1.21.1 still looks dark and patterned.
