About Huge Structure Blocks
From ModrinthStructure blocks. But bigger (and optimised). Up to 512 blocks!
Note: I am currently updating old versions to include the new optimisations and limit removals.
Huge Structure Blocks
Huge structure blocks increases the maximum structure block size and corner search radius to 512 blocks. Render of the bounding box is also increased to 256 blocks.
In short:
- Increases maximum structure size to 512 blocks.
- Increases render distance of structure bounding box to 256 blocks.
- Optimises the corner search algorithm
- Maintains a cache of structure block corners that allows for instant resolving.
- Removes the Jigsaw depth limit.
- Removes the 128 block distance limit from structure features/pools.
- Adds a creative item group for structure block items.
HSB's corner search resolves instantly versus Vanilla which takes seconds (sometimes even crashes). This is particularly useful on build servers where players have access to create structures.
