🧱 Just Block Shapes - Complete Your Building Palette
Every vanilla material deserves a full set of block shapes.
Just Block Shapes adds the missing walls, stairs, slabs, fences, fence gates, trapdoors, doors, pressure plates, and buttons for vanilla building blocks that should have had them all along. No new textures, no custom assets — every block looks like it was always part of vanilla Minecraft.
✨ Features
🧩 Missing Shape Variants

- Fences, Fence Gates for all targeted blocks
- Trapdoors, Doors, Pressure Plates, Buttons for most targeted blocks
🎨 Terracotta & Concrete — Full Shape Sets
All 16 dyed terracotta colors and all 16 concrete colors get the full treatment: stairs, slabs, walls, fences, fence gates, trapdoors, doors, pressure plates, and buttons.
Plain terracotta is also included.
🏗️ Vanilla-First Design
- Uses existing vanilla textures — no resource pack needed
- Block properties (hardness, blast resistance, sounds) match the base block exactly
- Standard vanilla recipe patterns (stonecutter support included)
- Blocks appear in vanilla creative tabs alongside their base blocks
