Light

What is a light for?​

  • Light is responsible for simulating lighting in three-dimensional environments, providing the visual appearance of more realistic and attractive scenes. Lights are used to illuminate objects, create shadows, and set the overall atmosphere of a scene.

Properties​

Type​

  • Determines the lighting types of light in the scene.

Point​

  • It refers to a source of lighting that originates from a particular location and spreads in all directions. It is useful for replicating the lighting of lamps, torches and similar objects, creating an omnidirectional light distribution from a specific focal point.

Diameter​
  • Determines the diameter of the point light in the scene.

Spot​

  • Refers to a lighting source that focuses in a specific direction, simulating a focused beam of light. Ideal for creating directional effects, the spotlight has a point of origin, a specific direction and an aperture cone, enabling the generation of shadows and light attenuation as needed in the three-dimensional scene.

Distance​
  • Determines the illumination distance of the spotlight in the scene.

Min angle​
  • Determines the minimum illumination angle of the spotlight in the scene.

Max angle​
  • Determines the maximum illumination angle of the spotlight in the scene.

Sun​

  • Refers to a lighting source that simulates sunlight, a global light that evenly fills the entire scene.

Intensity​

  • Determines the intensity of light in the scene.

Color​

  • Determines the color of light in the scene.

Shadow​

  • Refers to the shadows generated by the illumination of light.

Shadow strenght​

  • Determines the intensity of the shadow generated by the illumination of light in the scene.

Shadow resolution​

  • Determines the resolution of the shadow generated by the illumination of light in the scene.

Min bias​

  • Determines the minimum value of correction added to the depth calculation when rendering shadows. This helps move the shadows slightly away from the surface that is casting the shadow, thus avoiding z-fighting and shadow acne problems.

Max bias​

  • Determines the maximum value of correction added to depth calculation when rendering shadows. This helps move the shadows slightly away from the surface that is casting the shadow, thus avoiding z-fighting and shadow acne problems.

Visible distance​

  • Determines the distance of the shadow generated by the illumination of light in the scene that will be visible.

Blur​

  • Determines the intensity of the shadow blur generated by the illumination of light in the scene.

Shadow minimal distance​

  • Determines the minimum rendering distance of the shadow generated by the illumination of light in the scene.
