Application
Tessera
Pattern scans into seamless PBR tiles
A standalone Windows app that turns photos or scans of repeating patterns (fabric, wallpaper, decorative surfaces) into seamless, tileable textures, with one clean tile per material layer (diffuse, normal, bump, displacement), guided by a few lightweight hints.
Overview
Digitising a repeating surface into a clean, seamless tile is tedious manual work: offsetting and clone-stamping in Photoshop, eyeballing the exact repeat, and doing it all over again for every aligned layer (diffuse, normal, bump, displacement). Tessera automates the hard part. It detects the pattern's periodic lattice and reconstructs one seamless tile per layer, all kept in register, by averaging across many real repeats so scan noise, lint and uneven lighting fall away while the motif stays sharp.
It is algorithm-driven but hint-guided: you drop a few dots on a repeating feature, optionally mask out folds or defects and set a scale reference, and it fits the warp/weft period and a deformable mesh, then extracts the tile. Beyond the single tile it can assemble an arbitrary-size quilt with seam-aware blending, synthesise fabric that does not repeat exactly to any size, add subtle curl-noise warp so the weave is not a dead-straight CG grid, and preview the result as a lit PBR material in 3D. It is aimed at texture and material artists, and commercial fabric, textile and pattern shops digitising scans (e.g. Metis-class scanners) for 3D, CG and visualisation.
Features
- Hint-driven lattice solver: drop a few dots on a repeating feature and it fits the warp/weft period and a deformable mesh (flood-fill, then refine onto the actual threads)
- Automatic period finding via FFT-autocorrelation, plus an NCC template-match search across the scan
- Multi-layer extraction in register: diffuse, normal, bump, displacement and scalar each become a separate seamless tile, kept aligned, with per-layer colour and gamma rules
- Masks to exclude folds, dust, labels and defects from the tile average, with per-layer scoping
- Quilt: build arbitrary-size output from the tile with overlap and seam-aware blending
- Stochastic synthesis: generate not-exactly-repeating fabric to any size, with optional period-snapping for patterned cloth
- Curl-noise organic warp to break the perfectly-regular CG grid
- Built-in PBR 3D preview (base colour, normal, roughness, metallic, height) under studio HDRI lighting
- Scale-aware output (mm / DPI), ICC colour management, and TIFF / EXR / PNG export
- .tess project files, plus CLI ingestion of an image, a folder, or a multi-page TIFF (each page becomes a layer)
- Experimental, optional ML assists (predicted period and one-click auto-anchor placement), run on the CPU

FAQ
Do I need a special scanner?
No. Any photos or scans of the repeating pattern work. It's designed around commercial textile (Metis-class) scans but isn't tied to a specific device.
Does it need CUDA or a high-end GPU?
No. It needs an OpenGL 4.5 GPU for the viewport; the optional ML assists run on the CPU. Large scans simply benefit from more VRAM and RAM.
Can it output more than one material layer?
Yes. Diffuse, normal, bump, displacement and scalar layers are extracted as separate seamless tiles, kept in register, with per-layer colour handling and TIFF/EXR/PNG export.
Is it a Photoshop or Substance plugin?
No, it's a standalone Windows app. Feed it a folder or multi-page TIFF of your layers and it exports tiles you can bring into any DCC.
