Use stained glass with connected textures
Connecting stained glass blocks
Each stained glass color is treated as a separate block type by the resource pack. This means white stained glass connects to other white stained glass, but not to red stained glass or regular glass.
Design strategies
Create monochromatic windows. Build entire windows or walls from a single stained glass color to get the full seamless effect. A large wall of blue stained glass will appear as one unified surface rather than individual blocks.
Use color borders intentionally. Since different colors don't connect, you can create patterns by alternating stained glass colors. The visible seams between colors become a design feature rather than a flaw.
Combine with regular glass. Regular glass and tinted glass also don't connect to stained glass, so you can layer them for visual interest. For example, frame stained glass panels with regular glass to create distinct sections.
Plan color layouts ahead. Sketch your design before placing blocks. Decide which colors form large connected areas and which create accent lines or borders.
This approach works well for decorative windows, skylights, and colored light installations where you want both seamless areas and intentional visual breaks.
