The Is Tiling Middle Sections property controls whether the non-corner sections of a NineSlice are tiled (repeated) instead of stretched. By default this value is false, meaning the middle sections stretch to fill the available space. When set to true, the middle sections repeat their texture at its natural size instead of stretching.
This property appears in the Source category in the Variables tab.
This is useful for textures with repeating patterns like brick walls, chains, or borders where stretching would distort the pattern.
Two NineSlices, one streching and one tiling middle section
Default Behavior (Stretching)
By default, when a NineSlice is resized, the five non-corner sections (Top, Bottom, Left, Right, and Center) are stretched to fill the space between the corners. This works well for smooth or gradient textures, but can create visible distortion with patterned textures.
Tiling Behavior
When Is Tiling Middle Sections is set to true, the five non-corner sections repeat their texture instead of stretching:
Top and Bottom edges tile horizontally
Left and Right edges tile vertically
Center section tiles in both directions
The four corner sections (Top Left, Top Right, Bottom Left, Bottom Right) are never tiled — they always render at their natural size regardless of this setting.
