Mo Glass Mod — Guide
Mechanics
Seamless Transparency
One of the primary technical achievements of Mo Glass is its seamless transparency. In vanilla Minecraft, glass blocks hide their internal faces when placed next to other glass blocks. Mo Glass extends this logic to stairs and slabs. Whether you place a glass stair next to a glass slab, a full glass block, or another stair, the touching faces will become invisible, creating the illusion of a single, continuous piece of glass.

Working Translucency (Tinted Glass)
Tinted glass stairs and slabs retain the unique property of blocking light while remaining visually translucent. * Light Blocking: If placed in a way that leaves no air gaps (e.g., a solid wall of tinted slabs), they will completely block light from passing through. * Light Passage: If there is a gap in the geometry (such as the open space in a stair block), light will pass through that specific area.
Technical Details
The mod implements a complex custom rendering system to handle the transparency of non-full blocks. Because stairs can exist in 40 different states (direction, half, and shape) and slabs in 3 states, the mod must calculate transparency across thousands of potential neighbor combinations.
- Stair Scenarios: 10,800 possible neighbor scenarios accounted for.
- Slab Scenarios: 810 possible neighbor scenarios accounted for.
- Glass Block Adjustments: 270 scenarios (compared to 12 in vanilla) to ensure full blocks recognize the transparency of adjacent stairs and slabs.
