BrushFlow is a texturing tool that allows users to paint tangent normal maps directly onto 3D models or their corresponding UV maps. It features an intelligent curve interpolation system that automatically blends manual brush strokes to generate smooth, continuous details across the surface.

The tool includes a live stroke preview utilizing the Cycles rendering engine and offers customizable brush settings for adjusting radius, smoothing, and alpha levels. Completed tangent space normal maps can be exported at resolutions up to 4K for integration into external 3D software and game engines.
