Instant Meshes vs Mixos Mold

Instant Meshes is free, open-source software for interactive field-aligned mesh generation, available for Linux, macOS, and Windows. Its standard workflow solves an orientation field and then a position field before mesh export becomes available. Users can adjust fields with brush tools and inspect input meshes, computed fields, and output meshes in the Advanced panel. Its command-line interface includes controls for thread count, output face or vertex count, edge scale, symmetry types, and point-cloud neighbor count. The project provides precompiled 64-bit Intel binaries for the listed desktop systems. Linux use requires zenity. The dataset panel also requires downloading a dataset ZIP and keeping its datasets folder beside the application. Building from source requires CMake, plus Xcode on Mac, Visual Studio 2015 on Windows, or GCC on Linux. The software originated as part of a publication presented at SIGGRAPH Asia 2015. Its license permits redistribution and use of source and binaries subject to listed conditions, and the repository provides an Issues page for discussion.

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.
