TextureCraft

TextureCraft — Fast, Native, and Open-Source 3D Texture Painting (Substance Painter Alternative)

Developed entirely in Rust by the ArtCraft team, TextureCraft is a modern and open-source alternative to Substance Painter that allows 3D models to be textured with PBR (Physically Based Rendering) textures directly using layers and masks.
Key Features and Advantages

    Seamless Painting on a 3D Surface: Because the brush stamps work directly on the 3D surface, brush strokes seamlessly cross UV seam boundaries; thanks to camera angle protection, paint does not bleed onto the back of the model.

    GPU-Powered Fast Map Baking: Creates maps with features like ambient occlusion, curvature, and thickness using GPU ray tracing, which is approximately 12 times faster than CPU.

    High Performance at 8K Resolution: Thanks to its native display window supporting Metal, Vulkan, DirectX 12, and WebGPU, and its tiled texel engine running on every CPU core, it runs smoothly even with 8K texture sets.

    Advanced Format and UDIM Support: Imports glTF, FBX, COLLADA, USD, Alembic, OBJ, PLY, STL formats; offers PNG, JPEG, TGA, TIFF, EXR output (8/16/32 bit) and UDIM tile support.

    Built-in Path Tracing Rendering: Enables real-time rendering within the application using 256-sample GPU-based path tracing without needing to export models to another program.

Who is it suitable for?

    3D artists, game developers, digital modelers, and professionals who prefer the open-source ecosystem are looking for alternatives to expensive and cumbersome 3D texturing software.
