The short version
Adobe Substance 3D Painter is the desktop industry standard for 3D texturing - deep procedural materials, projection painting, a huge shelf, film-grade baking. Smart Material Studio's 3D Painter is a free browser tool that covers the common ground: hand painting, fill layers with mask generators, mesh baking and engine-ready export - with nothing to install.
Feature comparison
| Browser 3D Painter | Substance 3D Painter | |
|---|---|---|
| Install | None - runs in a browser tab | Multi-GB desktop app + account |
| Cost | Completely free - no account | Paid subscription |
| Hand painting | Colour + per-stroke rough/metal, blend modes, fill bucket, pen pressure | Full, plus stencils & projection |
| Fill layers + masks | Yes - generators (edge/cavity/AO), procedural noise, per-effect blend | Yes - the full generator/anchor system |
| Baking | AO, curvature, normal, position, ID, vertex colour (approximate AO) | Full high-to-low, path-traced AO, thickness |
| Paint across UV seams | Not yet (roadmap) | Yes - projection painting |
| Export | Textured .glb, PNG maps, packed ORM, project files | Every engine preset + .spsm |
| Privacy | Runs locally, nothing uploaded | Local desktop |
Who the browser painter is for
- Quick jobs - texture a prop or a low-poly asset without opening a heavy app.
- Low-poly and stylised work - hand-painted diffuse, flat shading, pixel filtering.
- Learning PBR - see how base colour, roughness, metallic and masks interact, free.
- No-install machines - Chromebooks, locked-down work laptops, a borrowed computer.
Who should still use Substance Painter
- Film and AAA pipelines that need deep procedural materials and film-grade bakes.
- Seam-critical work that needs to paint continuously across UV islands (projection painting).
- Studio pipelines already built around
.spsmsmart materials and export presets.
The two are not mutually exclusive. Smart Material Studio can design a material and export a Python script that rebuilds the layer stack inside Painter, so you can prototype in the browser and finish on the desktop.
Honest about what it is. This is a real browser texture painter, not a Substance 3D Painter replacement. The baked ambient occlusion is curvature-based (approximate, not path-traced), and a single brush stroke currently paints within one UV island - painting continuously across a UV seam (projection painting) is on the roadmap. For quick jobs, low-poly and stylised work, learning PBR, and no-install machines it does the job; for film/AAA-depth procedural work, keep Painter.
