What is Nack app for

[Ruslan]

Nack is an experimental offline mobile tool
designed to generate depth maps and normal maps
from a single photo using Shape-from-Shading techniques.

The app runs fully offline on the device
and is optimized for fast iteration and production usability
rather than physical accuracy.

Processing time is around 10 seconds per image
on a mid-range Android device.
No cloud, no uploads, no external servers.

This group is created for:
• Early testers
• Technical artists
• Graphics programmers
• Indie developers
• Anyone interested in depth / normal map workflows

As a tester, you can:
• Get early access to the app
• Test real production scenarios
• Report bugs and visual artifacts
• Influence feature priorities

Testing is done via Google Play closed testing.
