}

A conical spot light with inner/outer cone angles and optional cookie texture.

Fields

position: Vec3

direction: Vec3

color: Color

intensity: f32

radius: f32

inner_cone_angle: f32

outer_cone_angle: f32

attenuation: AttenuationModel

cast_shadows: bool

shadow_bias: f32

enabled: bool

cookie_texture_index: Option<u32>

Index into a cookie texture array. None means no cookie.
