NACK — Pro 3D & PBR Scanner - Instant Normal & Depth maps from a single photo

Stop overpaying for LiDAR. Nack uses advanced Computer Vision to extract high-fidelity 16-bit depth and normal maps from a single flash photo. While photogrammetry needs 50+ images, Nack’s SfS-algorithm reconstructs micro-surface geometry instantly. Key Features: • 16-bit PNG: Pro-grade HDR data for ZBrush/Blender. • PBR Ready: Instant Normal maps for Unity/Unreal. • No Hardware Limits: Works on any Android. • Sub-millimeter detail: Captures textures LiDAR misses. Perfect for 3D artists & QC.

Hi Product Hunt! 👋 I’m the creator of Nack, and I’m thrilled to share it with you today. As someone working with 3D, I’ve always found photogrammetry frustrating for small-scale surfaces. Taking 50+ photos just to get the texture of a rock or fabric is overkill, and LiDAR often misses those tiny, sub-millimeter details that make a material look real. That’s why I built Nack. It uses Shape-from-Shading (SfS) algorithms to reconstruct high-fidelity 3D geometry from just a single flash photo. No expensive sensors, no cloud processing—everything happens right on your Android device. Key things you can do with Nack: Generate 16-bit Depth Maps for precise sculpting in ZBrush/Blender. Extract instant Normal Maps for PBR workflows in Unity or Unreal Engine. Capture micro-textures that LiDAR simply can't see. I’m opening a demo period today: your first full-resolution export is on me! I’d love to hear your feedback on the reconstruction quality and see what kind of textures you’re capturing. I'll be here all day to answer your questions! 🚀
