Parallax occlusion mapped procedural bricks
In your harnessGodot shaderMIT
Brick wall with real-looking depth on a flat surface: the view ray is marched through a procedural brick heightfield in tangent space, so mortar lines sink, bricks occlude each other at angles, and the normal comes from the same height.
What it takes and gives
- Shader type
- spatial
- Parameters
- brick_color (vec4 = 0.62, 0.26, 0.18, 1), mortar_color (vec4 = 0.72, 0.7, 0.66, 1), bricks_across (float = 4), bricks_down (float = 8), mortar_width (float = 0.06), bevel (float = 0.08), depth_scale (float = 0.05), steps (int = 24) and 1 more
- Use it on
- A mesh with UVs and tangents (Godot primitive meshes have both).
- Result
- A red brick wall whose mortar lines look recessed and whose bricks occlude each other at angles.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified

Limits. The silhouette stays flat: only the interior of the surface shows depth. Shadows and depth are the flat surface's. Cost grows with steps. Strongly curved surfaces bend the illusion. The march runs in UV space, so non-square UV scaling skews the depth.
