Flattening a build site, sealing off awkward caves, or flooding terrain with water or lava is faster with Hole Filler Mod, a utility mod built around craftable throwables that fill holes for you. Its special orbs can build terrain back up with blocks, place invisible light sources, or remove those lights again, and any newly placed blocks can be canceled by hitting them within 15 seconds.
Key Features
- Turns hole filling into a quick throwable action, useful for flattening land, covering caves, and reshaping terrain without placing every block by hand.
- Includes a dirt-based filler that uses free dirt blocks, with fills of up to 500 blocks.
- Offers a selectable filler that can switch to a chosen block with Shift + right-click, as long as that block is in your inventory.
- Adds a smart filler that tries to match the blocks already in the area and uses blocks from your inventory, with fills of up to 500 blocks.
- Supports water and lava filling by placing ice or magma first, which later turn into water or lava, with fills of up to 500 blocks.
- Extends beyond terrain work with invisible light sources whose level can be changed via Shift + right-click, plus a darkening option that removes those lights.
