Falling Sand

Summary

Falling Sand is a simple mod that rewrites the logic for falling blocks. Most falling blocks such as sand and gravel will no longer be converted into entities when suspended in the air, they will instead stay as blocks and move down, and can now slide down hills and cliffs, adding landslides and sometimes even cave-ins. This can also improve performance with falling blocks in some cases, as they no longer spawn falling block entities! The mod can also be configured to apply these physics to any blocks you want!

Config
