Photo to Texture: PBR & Brush
JK3DA
Turn any photo into game-ready PBR texture maps, 16-bit sculpting brushes and transparent foliage cutouts — right on your phone, completely offline.
Point your camera at stone, wood, fabric, concrete, rust or soil and get a full material set in seconds. No account, no cloud, no subscription.
★ NO AI — JUST MATH
Every map is computed on your device with deterministic image-processing and computer-vision algorithms. No machine learning, no neural networks, no diffusion models, no cloud. The same photo always produces exactly the same result — private, reproducible and free of hallucinated detail.
★ FULL PBR TEXTURE SET
• Albedo / base color with automatic de-lighting
• Normal map (OpenGL and DirectX)
• Height / displacement map
• Roughness map
• Metallic map
• Ambient occlusion (AO)
• ORM packed map for Unreal, Mask Map for Unity
★ SEAMLESS & TILEABLE
One tap makes any texture tile without visible seams. A clone/retouch tool lets you fix the seam by hand, and the 3D preview highlights it so you can check the result.
★ LIVE 3D PREVIEW
Inspect your material on a sphere, cube, plane or torus knot. Adjust displacement, tiling and light angle, switch environments, check the tiling in a 3x3 grid.
★ SCULPTING BRUSH MAKER
Turn a photo into a 16-bit grayscale alpha for ZBrush, Nomad Sculpt, Blender or Photoshop. Depth, edge softness and invert controls, plus Sculpt / Photoshop / transparent alpha modes.
★ FOLIAGE CUTOUT (new in 4.0)
Photograph leaves, grass or a branch and get a transparent PNG ready to drop on a foliage card. Magic wand keys the background in one tap, a brush fixes what it misses, pinch to zoom in on the last stubborn pixels. Edge Padding bleeds the leaf colours smoothly out past the silhouette so mip-maps never pull dark halos in the engine — and you can see it in the preview instead of taking it on faith. An opaque RGB map and the opacity mask are exported alongside.
★ MULTI-LIGHT (photometric stereo)
Take 3–4 photos with the light moved between shots and the app solves for the true surface normals — measured geometry instead of an estimate.
★ EXPORT THAT FITS YOUR ENGINE
• PNG including real 16-bit grayscale (no banding)
• EXR (32-bit float) and TGA
• Engine presets: Unreal (ORM, DirectX normals) and Unity HDRP (Mask Map, OpenGL normals)
• Everything as one ZIP with correct suffixes
★ MADE FOR
3D artists, game developers, indie devs and students working in Blender, Unreal Engine, Unity, ZBrush, Nomad Sculpt, Substance, Godot, 3ds Max, Maya or Photoshop.
★ FREE — PRO IF YOU NEED IT
The core is free: all PBR maps, 1K and 2K, 16-bit PNG, all brush modes, seamless, ZIP export and the 3D preview.
Pro is a single one-time purchase (no subscription, ever): 4K export, EXR and TGA, batch processing for many photos at once, and the Unreal/Unity engine presets.
★ PRIVACY BY DESIGN
The app collects no data, requires no account and works in airplane mode. Your photos never leave your device.
