Lights

• Light
  Entity Component

  Light point_light

  A light with color and intensity. A point light by default, add a spot light component to add a cutoff. Can be parameterized to simulate the atmosphere sun.

  Schema

  color

  Vector3

  Default: [1,1,1]

  Light color.

  intensity

  Float

  Default: 1

  Light intensity.

  isDirectional

  Boolean

  Default: false

  Make this light directional, position is ignored in this case.

  isSun

  Boolean

  Default: false

  Make this light direction control the atmosphere sun direction. If more than one light is marked to be a sun results are undefined.

  range

  Float

  Default: 0

  The range for the point light. If the range is 0, then physically correct point light attenuation function is used.

    Shadow caster
    Entity Component

    Shadow caster shadow_caster

    Enables a light to cast shadows.

    Schema

    accumulateShadowCascades

    Boolean

    Default: true

    For directional lights, accumulate all shadow cascades.

    bias

    Float

    Default: 0.004

    Bias to apply to avoid self shadowing artifacts.

    cascadeCount

    Byte

    Default: [4] Quad Cascade

    [0] Static Shadow Map [1] Single Cascade [2] Dual Cascade [3] Triple Cascade [4] Quad Cascade

    For directional lights, number of cascades.

    cascadeSplitLambda

    Float

    Default: 0.94

    For directional lights, adjusts the distribution of cascade splits in Cascaded Shadow Mapping for directional lights. A value of 0 results in uniform (linear) splits across the view frustum, while a value of 1 skews the splits toward the camera, providing higher shadow resolution near the viewer and lower resolution in the distance. Intermediate values blend linear and logarithmic distributions for a balanced result. The value ranges from 0 to 1.

    farDist

    Float

    Default: 100

    Distance to the far plane.

    nearDist

    Float

    Default: 0.1

    Distance to the near plane.

    quality

    Integer

    Default: [1024] Low (1024x1024)

    [256] Ultra-Low (256x256) [512] Very Low (512x512) [1024] Low (1024x1024) [2048] Medium-Low (2048x2048) [3072] Medium (3072x3072) [4096] Medium High (4096x4096) [6144] High (6144x6144) [8192] Ultra High (8192x8192)

    Resolution of the shadow map.
