Wet surfaces

Paint water-coated materials with darker values, softened texture, and reflective highlights that follow form and gravity.

What it is

Wet surfaces combine the underlying material with a thin water layer. Moisture can darken local values, soften small texture, and add sharper, more mirror-like highlights.

Separate the base material, moisture darkening, and specular highlights, which are shiny reflections from the water. Water follows the surface plane and collects in edges, folds, and low spots. Raised areas dry sooner and appear more matte.

Puddles reflect the sky and buildings. Wet rocks retain bumps and cracks, while wet hair forms thicker clumps. Drips stretch along gravity, and droplets have small, bright highlights with crisp edges.

Why it matters

Wet-surface control helps you show rain, sweat, showers, puddles, and shorelines consistently. Weak control can make materials look generically glossy, plastic, oily, dirty, or simply darker.

You can check it when

• ✓Create dry and wet versions of the same object without changing its form or design. The wet version shows darker values, softened texture, and a reflective layer.
• ✓Show different wetness levels on one object while preserving the material identity. Puddles, drips, and droplets follow gravity, surface planes, nearby light sources, and environment colors.
