I'm ready to open up the app for community testing. If you want to try it out and help me refine the SfS logic "in the wild," you can join the beta starting today.

I ve been working on a project called Nack, and I wanted to share it with fellow creators who are struggling with low-quality texture generation.
The Problem: Most modern mobile scanners and generators rely on AI. While it looks cool at first glance, it often "hallucinates" details, creating blurry normal maps and physically incorrect geometry.
The Solution: I decided to go back to the roots. Nack uses a deterministic Shape from Shading (SfS) algorithm. No AI, no cloud servers, 100% offline. It extracts high-frequency details (pores, fabric weaves, stone grains) from a single smartphone photo in just 4-10 seconds.
