Curved world bend by camera distance

Bend everything that uses the material downward with the square of its horizontal distance from the camera, so the world curves away like a small planet or a rolling log, with a checker pattern to show the bend.

How it works

Shader type
spatial
Parameters
curvature (float = 0.02), sideways_curvature (float = 0), flat_radius (float = 2), color_a (vec4 = 0.85, 0.82, 0.75, 1), color_b (vec4 = 0.35, 0.55, 0.75, 1), checker_size (float = 1), roughness (float = 0.8)
Use it on
Meshes with enough vertices along the bend (the demo road has 200 rows); other scene materials need the same vertex code to match.
Result
A checkered road and blocks that curve down and to the side toward the horizon.

Limits to consider

Visual only: physics, raycasts and culling use the unbent positions, so objects near the frustum edge can pop. Normals are not updated for the bend. Large flat polygons do not bend; subdivide them.
