What This Mod Is

This mod is a curated set of block variants that Mojang has left out of the vanilla game.

What This Mod Is Not

This mod is not an exhaustive set of all alternate block types for all vanilla materials.
This is my take on adding block variants that I feel belong in the base game, and are based on the existing choices that Mojang have made for the current block set.

Showcase

Current Block Variant List

Below is a list of all variant blocks included in the mod.

New for v1.2.0

All glazed terracotta slabs

Slabs for all colors of Glazed Terracotta

  • Slabs respect placement orientation correctly
  • Double slabs will retain the facing orientation of the first slab placed in the world, regardless of direction the second slab is placed - this is the intended behavior

  • Slab
    • All vanilla logs
    • All vanilla wood blocks (bark texture on all 6 sides)

Known Issues

  • Nether Brick Fence Gate, Red Nether Brick Fence Gate, and Brick Fence Gate use the wrong sounds, using all standard Wood sounds.
    There are no existing non-wood gate opening or closing sounds.
    • Fun Fact: The vanilla codebase hard codes a requirement for all Fence Gates to have an associated WoodType.

Future Considerations

There are currently only a couple of features planned for a future update.

  • Add dripping tear effect to Crying Obsidian slab, stairs, and wall
  • Chiseled Red Nether Bricks
  • Correct block hit and break sounds for Brick and Nether Brick Fence Gates
  • Add a brick type sound for Nether Brick and Brick Fence Gates
