Curvy 3D vs Mixos Mold

Curvy 3D is a Windows sketch-based sculpting program aimed at first-time 3D artists. Users draw profiles and curves to make rounded or organic forms, then refine surfaces with Inflate, Deflate, Pinch, Smooth and Flatten warp brushes. Adaptive subdivision adds mesh detail where needed while controlling triangle counts. The program supports manual retopology, multiresolution sculpting and voxel sculpting. Texture tools paint color, specular and bump maps in 3D views or on 2D textures. Image Inflate converts silhouettes or greyscale images into 3D models using heightmap, bubble, bevel or extrude styles. Models export as OBJ for rendering or animation in software such as Blender. The maker also describes use with Blender or Bryce and importing characters from Poser or Daz. Curvy 3D 5 is listed for Microsoft Windows and requires a DirectX 8.0-compatible 3D graphics card. Aartform offers a free 30-day demo; the Curvy 3D 5 plan is a one-time purchase with price varying by location. Aartform describes itself as an independent London game development studio founded in 2003, and directs questions to its forum.

Mixos Mold is browser-based 3D sculpting software for shaping organic forms with GPU sculpting and pressure-sensitive brushes. Its toolset includes subdivision, dynamic topology, masking, symmetry, stamp alphas, brush presets, and remeshing. Users can import OBJ, FBX, or GLB models, unwrap a sculpt, and send it to Mixos Paint for layered PBR texturing. Mold runs without installation in a WebGPU-capable browser; desktop browsers listed are Chrome, Edge, Firefox, Brave, and Safari 26 or later. It also runs on iPad and Android in compatible browsers, and is included in the free Mixos iOS app for iOS 26 or later. Sculpting and saving to a library are free, but exporting finished meshes as GLB, OBJ, or STL requires a paid plan or perpetual license. Pro costs $8.99/mo, Max costs $17.99/mo, and a perpetual license costs $99 once. Account-saved projects can be opened across devices after sign-in. The maker says editing runs locally in the browser, but provides no equivalent security audit or uptime guarantee.
