2D lights and shadows

light2d and occluder2d build a light map every sprite, polygon and tile is multiplied by. Shadows come from the shapes a node has.

• light2d is point or directional, with color, radius, intensity and shadows. A point light fades quadratically to zero at radius, and unlit parts fall to the camera's ambient.

• An occluder2d left empty follows the node's collider2d, or its circle, capsule, rect or sprite. A directional light casts parallel shadows.

  

• post = ["bloom"] on the camera picks up an intensity past 1. ssao, ssr and dof are the 3D passes.

• In the editor, a Lights chip draws every light's reach and every occluder's resolved outline, and the Polygon tool traces an occluder in Points mode.

  

[nodes.light2d]
kind = "point"
color = "#ffd28a"
radius = 8.0
intensity = 1.6
shadows = true

Lights are outside the simulation. A scene with no light2d adds no pass. A frame draws at most 64 lights. Rendering has the rest.
