• Increased LOD rendering speed by about 20%-ish (results may vary).
• Fixed log spam and out-of-memory conditions when LOD mesh builder encounters an exception.
• LOD renderer is now compatible with Immersive Portals.
• Fancy waypoint renderer now disables itself when Immersive Portals is installed.
  • Non-fancy waypoint renderer remains active.
  • I might look into getting this to work better some other time.
• Fixed Create blocks showing up as fog-colored when LOD rendering is active.

For normal players:

• 1.21.5: Added leaf litter, wildflowers, cactus flowers, bushes, firefly bushes, and dry grass.
  • Added 3 new wildflower colors, in addition to the vanilla yellow/white ones.
• Fixed pale netherrack textures in old MC versions. Again.
• LOD rendering now has fog.
  • Density parameters are configurable.
• Possibly fixed LOD renderer causing crash on some hardware/OS/JVM combinations.

For data pack developers:

• Ores (and possibly other things that map blocks to other blocks) can now use tags for the block to map from.
• Fixed being unable to use wood palettes in overriders.
• Added nullable casting syntax: Type?(expression) casts expression to Type, or evaluates to null if the expression cannot be cast.
• Improved error reporting when failing to compile column values.
• Possibly fixed issue with syncing booleans to the client for constant column values/decision trees/etc...
