FNViaViewer

For Minecraft 1.21.7 to 26.2 (Fabric), joins 26.3 servers. One file for every version: Fabric loads only the part for your game.

• More client versions: besides 1.21.11, it now works on 26.2, 26.1.x (26.1–26.1.2), 1.21.9–1.21.10 and 1.21.7–1.21.8. Each one only adds what that version is missing up to 26.3.
• Mobs that older clients don't have are drawn with their real shape instead of ViaBackwards' look-alike:
  • 1.21.7–1.21.10: nautilus (and its baby), zombie nautilus (normal and coral), camel husk and parched;
  • 1.21.7–1.21.8: copper golem, with its oxidation stage and glowing eyes.
• Their shapes and animations come from Mojang's official Bedrock samples (bedrock-samples), downloaded on first launch like the other assets and checked against their SHA-1. Nothing from Mojang is bundled in the mod.
• 26.3 models and item definitions are converted for older clients: tilted cubes beyond 45° (signs, hanging sign chains), the "on shelf" display context and new armor trim colors.
• 1.21.7–1.21.8: shelves are shown as plain blocks (no items on top), and copper chests and copper golem statues keep ViaBackwards' look-alike (a chest...), because that version has no renderer for them.
• 26.1 and newer already have the new babies, and 26.2 and newer the sulfur cube and the new signs: those features are only added where they are missing.
• Tested in game on 1.21.11. The other versions start and load correctly, but haven't been played on a server yet: please report anything odd on GitHub.
