RepeaTile is an addon that automates the setup and construction of tileable 3D surfaces. It establishes a non-destructive rig for building source geometry used in tileable materials and trim sheets, allowing users to define tile counts and grid step sizes across the X and Y axes.

The toolset provides boundary controls that constrain objects within the main tile area while moving, rotating, or scaling, using either strict clamping or adaptive fitting. It includes intersection-free randomization for scattering objects across the grid, with options to limit movement to specific axes or selected objects. Visual aids such as customizable viewport overlays and boundary frames help differentiate active geometry from repeated instances. When a layout is finalized, the setup can be baked into static geometry, including a clean bake option that automatically deletes exterior geometry unnecessary for texture baking or sculpting.
