Smooth Spheres
Smooth Spheres adds decorative smooth sphere blocks to Minecraft 1.21.4 with Fabric.
Features
- 9 smooth sphere blocks
- Metal, chrome, ceramic, obsidian, crystal, glass, frosted glass, and glowing variants
- Custom creative tab
- Lightweight physics system
- Right-click sphere blocks to launch them as physics spheres
- Right-click physics spheres to launch them again
- Push physics spheres by walking into them
- Arrows, fireballs, eggs, and other projectiles can push physics spheres
- Left-click physics spheres to break them and drop the matching item
- Mod Menu configuration support
- Toggle physics on or off in-game
- Select sphere model quality: Balanced, High, or Ultra

Notes
Real PBR effects depend on shader/resource-pack support such as Iris-compatible shaders. Without shaders, the mod still works with normal vanilla-style rendering.
This mod uses lightweight Minecraft entity physics, not a full rigid-body physics engine.
