[2.4.20] fabric 1.20.1 v2.4.20
by 1whohears on Jun 15, 2026
Download
- Custom preset types can now be added in addon mods
- Added a Simulated Entity System. This is based on the old simulated missile system in DSC that allowed missiles to continue moving in unloaded chunks.
- Added the Distant Visible Manager. This will replace the client side raycast system. Raycasts are now added to a queue. Blockstate checks are limited to some number per tick (
/gamerule onewholibs:max_raycast_block_checks). Incomplete raycasts will be completed on the next tick. - Instead of relying on Distant horizons on the client side to do distant raycasts, the server side now generates a low level of detail height map of the entire world. It gets updated when chunks are loaded.
- Use
/create_lod_height_map_imageto see the currently loaded height map. - If the world already exists use
/gen_lod_height_map [diameter] [center]to load all the chunks inside that box and fill in the height map
