Surface is an add-on that automates the application of displacement textures to 3D models. It interfaces with Blender's Displace and Subdivision modifiers, allowing users to adjust modifier settings directly from its panel.

The add-on includes a library of over 1,200 alpha displacement textures organized into 24 categories. These textures can be applied to meshes using the add-on interface or used independently within Blender or other 3D software. The texture library covers a wide range of surfaces, including rock, skin, ground, wood, metal, leather, fabric, bricks, ornaments, and reptile skin.
