About this project
What does CrystalBlocks add?
Crystal Blocks
Vanilla building block sets don't leave much room for texture variety once you've used up stone, brick, and quartz. This mod adds 7 more block families, each in 6 colors, so you've got somewhere to go once you've built the same three houses out of the same three materials.
Available for 1.20.1, 1.12.2, and 1.7.10. No mechanics, no gimmicks, just blocks.
Families
| Family | Look | Crafted from |
|---|---|---|
| Crystal | glowing diagonal vein in stone | stone + dye |
| Speckle | scattered mineral flecks | cobblestone + dye |
| Brick | offset masonry, proper mortar lines | bricks + dye |
| Corroded | blotchy rust patches | iron nugget + dye* |
| Mossy | patchy organic overlay | mossy cobblestone + dye |
| Marble | flowing curved vein | quartz block + dye |
| Hexplate | honeycomb plating | iron ingot + dye |
*Corroded uses redstone instead on 1.7.10 - iron nugget didn't exist as a craftable item until 1.8, so that version subs in redstone instead. 1.20.1 and 1.12.2 both use the real iron nugget recipe.
Each family comes in cyan, red, green, purple, orange, and blue. Each color gets the full building set: block, slab, stairs, fence, fence gate, wall.
Glow variants
Every family also has one glowing block, crafted with glowstone dust instead of dye, full light level. Glow variants get block, slab, and stairs — no fence/gate/wall. Nobody's building a glowing fence line, so that set stayed out on purpose.
Details that matter
On 1.20.1, slabs waterlog properly - place one in water and it holds like a vanilla slab. Fences, gates, and walls waterlog too, though that's their vanilla base classes doing the work, not something built for this mod specifically. Waterlogging is a 1.13+ feature, so neither the 1.12.2 nor the 1.7.10 download includes it - not a bug, just doesn't exist at those versions.
Everything drops itself when broken. All blocks live in their own creative tab instead of getting buried in vanilla's building blocks tab.
The screenshot is just an example of how it looks — there's too many blocks to screenshot all of them here.
