Vulcanus Lava Fill

Factorio 2.x / Space Age mod that adds a dedicated lava fill item for Vulcanus.

What It Does

• Adds Vulcanus lava fill, crafted from stone and calcite.
• Places a dedicated vulcanus-lava-fill foundation-style tile.
• Can cover both lava and lava-hot tiles.
• Sets Vulcanus lava's default cover tile to the new tile, improving force-build and blueprint workflows.
• Uses vanilla tile ghosts and place_as_tile, so construction robots and blueprints work normally.
• Has no on_tick logic. A tiny control script only refreshes the recipe unlock when the mod is added to existing saves.

Unlock

The recipe unlocks with calcite-processing.

Recipe

• 10 stone
• 1 calcite
• Produces 5 Vulcanus lava fill
