# Real-Time PBR Texture Authoring and Normal Map Generation in WebGL2 (Part 12) Game artists, 3D environment designers, and architectural visualizers need fast, deterministic surface maps without round-tripping heavy files through cloud queues. By using a [automatic seamless tileable texture synthesis tool (60)](https://normalmapai.com/seamless-texture), creators can generate tangent-space normal maps, height maps, ambient occlusion, and packed ORM textures directly on their local GPU. ## Key WebGL2 PBR Map Workflows Modern physically based rendering engines (Unreal Engine 5, Unity URP/HDRP, Blender, Godot, and Three.js) rely on calibrated surface maps: - **Tangent-Space Normal Extraction**: Convert diffuse photos or stylized textures with the [OpenGL and DirectX normal map Y-channel flipper (60)](https://normalmapai.com/normal-map-inverter), featuring Sobel/Scharr gradient filters, multi-pass detail sliders, and live 3D sphere/cube/plane lighting previews. - **Channel Packing & Seam Removal**: Prepare production-ready assets using the [3D printable relief and lithophane height map generator (60)](https://normalmapai.com/3d-print-height-map) so roughness, metallic, and ambient occlusion maps share a single optimized texture sampler. - **DirectX / OpenGL Handedness Control**: Toggle green-channel (+Y / -Y) orientation on the fly and export 8-bit or 16-bit PNGs with zero server uploads. ## Practical Production Steps 1. **Import Any Albedo or Height Photo**: Drag a PNG, JPEG, or WebP surface image into the browser viewport. 2. **Tune Fine & Macro Surface Relief**: Adjust strength, blur-sharp balance, and height depth while inspecting specular highlights under a rotating point light. 3. **Export PBR Texture Pack**: Download individual Normal, Height, AO, Roughness, or combined ORM maps ready for immediate engine import.
