Diorama

Diorama 0.1.1 fixes a big slowdown while exploring, and adds Minecraft 1.21.11.

Download the jar for your Minecraft version:

• diorama-0.1.1+26.3.jar for Minecraft 26.3
• diorama-0.1.1+1.21.11.jar for Minecraft 1.21.11

Both need Fabric Loader 0.19.5 or newer and Fabric API. Put the jar and Fabric API in .minecraft/mods.

What's new:

• Minecraft 1.21.11 support.
• Quality setting: Fancy or Fast. Fast is for slower computers: the map fills in faster and the fog costs less to draw.

Fixed:

• Exploring new terrain could drop the game to 15 fps, with freezes of over a second. Diorama was working out biome colours on the game's main thread. That work now runs in the background, and flying over new land stays smooth.
• The minimap redrew its fog every frame, even when nothing had changed.
• Some chunk edges showed the wrong grass or water colour when a neighbouring chunk loaded after them.
