### Remarks

This is the default interaction mode for sprites, and all existing sprites will have this value. If the sprite is expected to show some interaction with masks, then [SpriteMaskInteraction.VisibleOutsideMask](/engine/6000.7/script-reference/unityengine/spritemaskinteraction/visibleoutsidemask.md) and VisibleUnderMask should be used.
