The Lumite Roof is a slanted building-block with violet, blue and pale blue rhombus-shaped tiles.
This slanted block can be placed to create corners of walls or for other purposes too when being rotated by pressing and holding R (as the default key) while moving the mouse.
It can be crafted in your Crafting Menu (default key "q"), but only after the crafting-recipe has been unlocked by
- creating Diamond Rods by putting Diamond bars into a Processor. Diamond Ore can be extracted from Nodes found on the Lava layer underground or made from Coal Nodes with Fire Bombs
- smelting Lumite bars in a Forge from Lumite Ore that can only be extracted from Lumite Nodes on the Corruption layer underground
- creating Lumite Slabs by putting Lumite bars into a Processor
- crafting or taking Diamond Roofs (unlocked after crafting Obsidian Roofs)
To craft 8 (blocks of) Lumite Roofs, you'll need
- 2 Lumite Rods made of Lumite bars in a Processor
- 4 Lumite Slabs made of Lumite bars in a Processor
- 1 Diamond Rod made of a Diamond bar in a Processor
- 1x Melted Wax made of Beeswax in a Forge or looted from Wood Treasure Chests or Stone Treasure Chests
Since R42 in May 2017, inner and outer corners blocks can be created for these roof blocks too by putting them into a Processor. No crafting recipes are required for this.
