NormalMap Pro

Turn any grayscale heightmap into a game-ready normal map in seconds. NormalMap Pro gives you two tools in one: a Python CLI with batch mode, adjustable strength, seamless tileable wrap-sampling, and a green-channel flip for OpenGL/DirectX workflows — plus a drag-and-drop HTML GUI that runs entirely in your browser with zero install. Both use the identical Sobel-based algorithm, verified pixel-for-pixel by automated cross-tests, so what you preview is exactly what the CLI bakes. Perfect for indie game devs, 3D artists, and texture tinkerers who want fast, local, no-subscription normal map baking.
