Bas Relief is a Blender add-on for turning images into displaced relief meshes from inside the 3D Viewport. Working from the Bas Relief tab in the N Panel, you click Import Image to load a PNG, JPG, BMP or TIFF, then Run Bas Relief to create a subdivided plane with a Displace modifier configured from that image. The plane matches the source aspect ratio automatically, and Subdivision Cuts, Subsurf Levels and Displace Strength are adjustable in the Adjust Last Operation panel.
Beyond the mesh, Create Texture builds a PBR material with an Image Texture node, while Create Depth Map sets up an orthographic camera, a Suzanne preview mesh and the Depth_Map_Comp_GN compositor node group at 500×500 and 16-bit depth. Two display options set Display Device to Display P3 and View Transform to Raw before you Render and Save the result.
Each Run Bas Relief click produces an independent plane with a uniquely named texture, so multiple reliefs coexist in one project. An optional AI-powered Height Map Generator built on the MiDaS model is available as a separate download from the developer's GitHub repository. The extension is released under the GNU General Public License v3.0 or later.
