# NormalMapAI: WebGL2 Browser Studio for 16-Bit Height Maps & Full PBR Textures Creating physically based rendering (PBR) materials for real-time 3D engines and relief height maps for 3D printing traditionally requires heavy desktop software or cloud subscription tools. When you need to quickly convert a 2D surface photograph into a complete material pack or a 16-bit displacement map without banding, uploading multi-megabyte textures to remote queues slows down iteration. With the [WebGL2 16-bit 3D print relief height map and PBR generator](https://normalmapai.com/3d-print-height-map) and the [online grayscale bump map and surface detail generator](https://normalmapai.com/bump-map-generator), 3D artists, game developers, and makers can generate production-ready texture maps 100% locally in the browser using hardware-accelerated GPU shaders. --- ## Key Capabilities & Map Outputs ### 1. Tangent-Space Normal & Grayscale Bump Maps - **Dual Engine Conventions**: Switch seamlessly between OpenGL (`+Y` green channel for Blender, Three.js, Godot, and Unity) and DirectX (`-Y` green channel for Unreal Engine 5). - **Multi-Scale Detail Filtering**: Blend fine micro-surface grain with broad structural relief using real-time Sobel and Scharr gradient filters. ### 2. True 16-Bit Displacement & 3D Print Relief Height Maps - Standard 8-bit grayscale height maps only provide 256 luminance steps, causing visible stair-stepping ("terracing") on displaced meshes and lithophane/relief 3D prints. - NormalMapAI exports true 16-bit PNG height maps (65,536 levels) directly from the GPU framebuffer for smooth subdivision displacement in Blender and crisp CNC/FDM relief meshes. ### 3. Complete PBR Material Pipeline - **Roughness, Ambient Occlusion (AO) & Metallic**: Extract physically plausible surface response maps from a single diffuse/albedo image. - **ORM Channel Packing**: Pack Ambient Occlusion (R), Roughness (G), and Metallic (B) into a single optimized texture for Unreal Engine 5 and glTF 2.0 web viewers. - **Seamless Tileable Synthesis & Transparent Decals**: Remove edge seams with mirror/blend tiling and strip backgrounds for decals and foliage cards. --- ## Step-by-Step Workflow for Blender, UE5 & 3D Printing 1. Launch the [browser-based normal map and PBR texture generator studio](https://normalmapai.com/) with zero login or installation. 2. Drop any 2D texture, photo, or height map into the workspace. 3. Preview the material in real time on a 3D sphere, cube, plane, cylinder, or torus under interactive HDRI and point lighting. 4. Adjust strength, bevel smoothing, and frequency sliders, then export individual maps or a complete engine-ready ZIP bundle.
