Seamless Texture Maker is a desktop material authoring utility for turning photographs and surface scans into tileable textures and PBR surface maps. An independent open-source Linux alternative for material tile synthesis, illumination balancing, and surface map generation, it runs 100% locally.

Key Features:

• Seamless Tile Synthesizer: Half-width wrap synthesis with cosine cross-blend feathering, Mirror-Quad kaleidoscope tile mode, high-pass illumination equalizer to remove uneven lighting gradients, and an adjustable blend-width slider.
• 3x3 / 4x4 Tile Preview & PBR Maps: Live interactive 3x3 and 4x4 tiled viewport proving zero seam lines, plus Sobel-derived Tangent-Space Normal Map, Height/Bump Map, and Roughness Map previews.
• Texture Set Exporter: Batch exports Diffuse Tile, Normal Map, Height Map, Roughness Map, and 3x3 Proof images in PNG, WebP, or JPEG formats.
