• High-quality PBR rendering
View models with base color, metallic/roughness, normal maps, occlusion, emission, alpha modes, and vertex colors. A procedural studio environment provides natural lighting and reflections without external HDR files.

• Studio and Geometry modes
Switch between Studio mode for material and texture inspection and Geometry mode for a clean, facet-colored view with visible edges.

• Fast, touch-friendly inspection
Orbit with one finger, pinch to zoom, double-tap to focus a mesh, and select or hide individual meshes from the mesh list.

• Orientation and navigation aids
Use the on-screen grid, axis gizmo, and axis-aligned grid controls to orient your model and inspect it from any angle.

• Manage multiple meshes
Load several models at once, isolate or hide parts, invert the selection, delete what you do not need, and keep the scene organized.

• Convert and export
Export selected meshes to another format. Choose the file name and destination through Android's system file picker.

• No account required
FormalMesh Viewer does not ask you to create an account or sign in. Your 3D files are processed locally on your device and are not uploaded to our servers.

• Privacy-friendly by design
The app uses Android's system file picker, and your files never leave your phone. No ads, no tracking, and no unnecessary storage permissions.

• Works offline
Open and inspect meshes without an internet connection. Google Play Billing is used only for the optional Premium purchase and to verify it.
