Twist deformation around the vertical axis
In your harnessGodot shaderMIT
Twist a mesh around its object Y axis by an angle that grows with height, with an optional wobble over time, rotating normals along so lighting follows the spiral.
What it takes and gives
- Shader type
- spatial
- Parameters
- albedo (vec4 = 0.85, 0.55, 0.25, 1), stripe_color (vec4 = 0.3, 0.15, 0.08, 1), twist_degrees_per_unit (float = 160), pivot_height (float = -0.6), wobble_degrees (float = 30), wobble_speed (float = 1.5), stripes (float = 6), roughness (float = 0.5)
- Use it on
- A mesh with enough vertical subdivisions (the demo box uses 48).
- Result
- An orange and brown striped bar twisted into a spiral that winds back and forth.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement

Limits. Normals ignore the shear term of the twist, so strong twists look slightly off in lighting. Collision and culling use the untwisted shape. Low vertex counts produce faceted spirals.
