Key Features & Workflow

1. Brushes & Textures

• Custom Brushes:

  • Locate brush presets (e.g., watercolor, pencil) in the tool panel. Adjust size, opacity, and spacing.

  • Import custom textures via Texture Settings to create unique strokes.

• Real-Time Preview:

  • Paint directly on the model in Texture Paint mode. Ensure you’re in Material Preview or Rendered View (Eevee recommended for real-time performance).

2. Layer System

• Layer Management:

  • Add/remove layers via a layer stack panel. Adjust blend modes (e.g., Multiply, Overlay) and opacity per layer.

  • Use layer masks for non-destructive editing.

• Material Setup:

  • The add-on may auto-generate a material with layer nodes. Verify this in the Material Properties tab.

3. Stylized Effects

• Presets:

  • Apply watercolor (soft edges, blending), pencil (hatching), or cel-shading (flat colors) from preset menus.

  • Tweak parameters like texture scale, color variation, and edge sharpness.

• Shading Adjustments:

  • Combine with Blender’s Shader Editor to mix NPR paints with procedural textures.

Troubleshooting

• Paint Not Visible:

  • Ensure the object has a valid UV map and the correct material assigned.

  • Check if the paint layers are masked or opacity is set to zero.

• Brush Issues:

  • Verify texture assignments in Brush > Texture settings. Reset to default if missing.

• Performance:

  • Reduce viewport resolution or layer count for complex scenes. Use fewer high-resolution textures.

Advanced Tips

• Integration:

  • Use painted textures as masks for modifiers (e.g., Displacement) or particle systems.

  • Bake textures (Image > Bake) for export to other software.

• Documentation:

  • Review included guides or video tutorials (if provided) for niche techniques like animating painted strokes.
