Free 3D sculptingsoftware, online.

A browser with WebGPU — current Chrome or Edge on Mac, Windows, or Linux. There is nothing to download and no plugin to install. Mold also runs on iPad and phones with a touch-first layout, including Apple Pencil pressure.

Mold runs on iPad in Safari or Chrome with a layout built for touch — the tool rail collapses into a dock, brushes respond to Apple Pencil pressure and tilt, and two fingers orbit the model while the pen sculpts. There is no App Store download; you open a tab and start. It is the same sculpting engine as on desktop, so a sculpt started on an iPad opens on a Mac or PC exactly as you left it.

Yes, on any device whose browser provides WebGPU — that covers recent Android phones and tablets on Chrome, and Chromebooks on a current ChromeOS. Because the engine is the browser's, there is no separate Android build to install and nothing to sideload. If your device's browser can't provide WebGPU, Mold says so on arrival rather than failing halfway through a stroke. Very dense sculpts want a capable device, but blockouts and mid-detail work are comfortable on modern hardware.

Yes. Mold exports STL, the standard 3D-printing format, as well as OBJ and GLB, and its voxel remesh produces the kind of watertight, evenly-tessellated mesh a slicer wants. Sculpting and remeshing are free; downloading the finished STL is part of a paid plan.

Less than most people expect. Digital sculpting maps onto a physical intuition you already have — you push, pull and smooth a surface rather than editing vertices and edge loops the way traditional 3D modelling does. The usual barrier isn't the concept, it's the setup: buying software, installing it, and finding a machine that runs it. Mold removes that step, so a first sculpt is a browser tab away, and the Mold manual walks through the fundamentals in order.

For the fundamentals, yes — brush sculpting with pressure and falloff, masking, mirror and radial symmetry, multiresolution subdivision, dynamic topology, and voxel/quad remeshing, all in a browser tab. ZBrush still goes deeper for professional character pipelines; Mold trades that depth for zero install and a built-in path to texturing.

One click unwraps the sculpt with fresh UVs and opens it in Mixos Studio, the layer-based PBR texture painter — paint materials, add masks and wear, then export standard texture maps for Blender, Unreal, Unity, and more.

Multiresolution subdivision takes a base mesh into millions of triangles. The engine displaces vertices on the same WebGPU device that renders the viewport, so brush strokes stay responsive on dense meshes.

Yes. Sculpting in Mold is free on every account — all the brushes, subdivision levels, dynamic topology, remeshing, masking and symmetry, with no time limit and no watermark on your work. You need a free Mixos account so your sculpts are saved to your library. Exporting the finished mesh as GLB, OBJ, or STL is on the paid plans.

Downloading the mesh (GLB, OBJ, or STL) is part of a Mixos paid plan — Pro, Max, or Team. Sculpting, saving to your library, and sending the sculpt to Mixos Studio for texturing all stay free, so you can take a model from blockout to textured before deciding whether to subscribe.
