What SculptGL is

SculptGL is a free digital sculpting app that runs in a browser using WebGL and JavaScript. Its tools include Brush, Inflate, Smooth, Twist, and Drag, with undo and redo for editing. Vertex painting supports color, roughness, and metalness, and tools can use alpha textures. Multiresolution sculpting uses Catmull-Clark and Loop subdivision and retains changes when moving between levels. Voxel remeshing uses SurfaceNets to make quad-only meshes, while dynamic topology applies local subdivision and decimation in real time using triangles; both approaches delete UVs. SculptGL imports and exports OBJ, PLY, and STL files and reads vertex color. The maker offers a standalone version described as identical to the web app, with 32-bit and 64-bit Windows downloads, and a Chrome Web Store extension. Users can customize camera, rendering, language, display options, and shortcuts through URL settings. The maker says the project is no longer maintained except for small fixes, and its repository was archived on January 17, 2026.
