A Projector allows you to project a Material onto all objects that intersect its frustum. The Material must use the Projector/Light or Projector/Multiply shaders, available in Unity’s Standard Assets.
You can use a Projector to create:
The Projector component is only compatible with the Built-in Render Pipeline and the availability of a alternative solution depends on which render pipeline you are using.
|Render pipeline||Post-processing support|
|Built-in Render Pipeline||The Built-in Render Pipeline is compatible with the Projector component.|
|Universal Render Pipeline (URP)||URP is not compatible with the Projector component. URP does not currently include an alternative solution.|
|High Definition Render Pipeline (HDRP)||HDRP is not compatible with the Projector component. However, HDRP includes the Decal Projector component which you can use to project Materials into your Scene.|
Standard Assets contains example Prefabs 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||Объекты, находящиеся перед ближней отсекающей плоскостью не буду проецироваться на.|
|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 Ratio||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:
