Note: Projector components are compatible only with the Built-in Render Pipeline. You cannot use Projector components in Projects that use the Universal Render Pipeline (URP) or High Definition Render Pipeline (HDRP).
A Projector allows you to project a MaterialAn asset that defines how a surface should be rendered, by including references to the Textures it uses, tiling information, Color tints and more. The available options for a Material depend on which Shader the Material is using. More info
See in Glossary onto all objects that intersect its frustum. The Material must use the Projector/Light or Projector/Multiply shadersA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info
See in Glossary, available in Unity’s Standard Assets.
You can use a Projector to create:
Standard Assets contains example PrefabsAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary that demonstrate the use of Projector components.
To use the Prefabs:
You can use the Prefab as is in your Project, modify it, or examine it to see how it is configured.
|Near Clip Plane||Objects in front of the near clip plane will not be projected upon.|
|Far Clip Plane||Objects beyond this distance will not be projected upon.|
|Field Of View||The field of view in degrees. This is only used if the Projector is not Orthographic.|
|Aspect RatioThe relationship of an image’s proportional dimensions, such as its width and height.
See in Glossary
|This allows you to tune the height and width of the Projector.|
|Orthographic||If enabled, the Projector will be Orthographic instead of perspective.|
|Orthographic Size||The Orthographic size of the Projection. This is only used if Orthographic is enabled.|
|Material||The Material that will be projected.|
|Ignore Layers||Objects in Layers that you specify here will not be projected upon. The default value is None.|
When configuring a Material to use with the Projector/Light and Projector/Multiply shaders, be aware of the following:
Falloff texture (if present):
