Lighting and shadow

Lighting

Lighting v2 The lights in your scene inform the lighting (and therefore the shading) of materials that utilize scene lights (Simple and PBR). These lights can create specular highlights and also optionally cast shadows!

Add a light to your scene

You can add a light to the scene by clicking +Add object > Scene, and selecting one of the available light types. Alternatively, you can add a light by right clicking in the Hierarchy panel, hovering your mouse over Scene, and clicking the type of light you want to add.

Types of light sources

You can add different types of light by clicking + Add object > Scene > XXXX Light.

Directional light

A directional light is one that acts as a large, faraway light source, like the sun. It casts even, uniform light from a specific direction. This light is also informed by your object’s transform rotation.

Directional light properties

  • Intensity: The brightness of the light source.
  • Color: The color of the light.
  • Cast shadow: This determines whether or not this light emits shadows. See the Shadows guide for more information.

Spot light

A spot light is a cone-shaped light that sends light from a single point in a specific direction, falling off as it gets farther from its point of origin. Think of a flashlight or a theatrical spotlight.

Spot light properties

  • Intensity: The brightness of the light source.
  • Color: The color of the light.
  • Attenuation Range: The range of the light cone, which will inform the fall off.
  • Inner angle: The angle of the inner attenuation, which will inform the beginning of the light spot.
  • Outer angle: The angle of the outer attenuation, which will inform how far out the edge of the light spot extends.

Point light

A point light is a point in 3D space that sends light out equally in all directions

Point light properties

  • Intensity: This determines how bright the light source is.
  • Color: The color of the light.
  • Attenuation Range: The range of the light sphere, which will inform the fall off.
