Custom Brush 'Texture Sandwich'

Add believable texture without losing form.

The Workflow

1. Keep form on normal layers.
2. Add a “texture” layer above, set to Overlay/Soft Light.
3. Paint texture with a gritty brush at low opacity.
4. Mask it so texture follows planes (more on light-facing areas, less in shadow).

The Usage

Texture should support form, not replace it. This keeps your painting readable and detailed.
