Aligning Windows with Direct Sunlight
Candela Shaders casts colored shadows that change tint when sunlight passes directly through stained glass blocks. Because this effect relies on the sun's angle rather than torches or lanterns, window orientation determines when and where colored patterns appear indoors. In vanilla Minecraft, the sun rises in the east and sets in the west. Build stained glass walls on eastern or western facades to project long tinted shadows across rooms during morning and late afternoon, or install overhead stained glass skylights to catch midday sunlight straight from above.
Choosing Surfaces That Highlight Tinted Light
Tinted shadows stand out sharpest when cast onto pale, neutral vanilla blocks. Place smooth quartz, white concrete, sandstone, or birch planks along the floor where sunlight lands so the shifted colors stay vivid instead of blending into dark stone or deep wood tones. You can arrange different colors of stained glass blocks side by side in large windows, greenhouses, or ceiling domes to create multi-colored floor patterns without overloading your graphics card. Remember to test your window designs during clear daytime weather, since overcast rain and nighttime remove direct sunlight beams.
