Plugin layout

The production Krita plugin lives under pykrita/advanced_erosion_generator/. The tests/ directory remains prototype-only reference code and is not imported by the plugin.

Installing in Krita

Copy pykrita/advanced_erosion_generator.desktop and the pykrita/advanced_erosion_generator/ folder into Krita's pykrita directory. The current plugin implementation is pure Python and does not depend on numpy or the test virtual environment.

Current UI

The plugin adds Tools > Scripts > Generate Advanced Erosion Terrain and uses the active document resolution as the terrain output size.

Controls:

• Generation Scale
• Erosion Scale
• Random Seed with a randomize button
• Advanced dropdown with Strength, Gully Weight, Detail, and Octaves
