RenderTexture Class, inherits from Texture

Render textures are textures that can be rendered to.

They can be used to implement image based rendering effects, dynamic shadows, projectors, reflections or surveillance cameras.

All rendering goes into the active RenderTexture (active class property). If the active RenderTexture is null everything is rendered to the main window.

Note that while RenderTexture assets can be only power-of-two size, it is possible to create a non-power-of-two (rect) render textures from scripts. These are most often used for image post processing effects.

RenderTexture class is only available in Unity Pro.

Variables
width

The width of the render texture in pixels.

height

The height of the render texture in pixels.

depth

The precision of the render texture's depth buffer in bits (0, 16, 24 are supported)

isPowerOfTwo

Is the size of the render texture constrained to power of two sizes?

format

The format of the render texture.

useMipMap

Generate mipmap levels?

isCubemap

If enabled, this Render Texture will be used as a Cubemap

Constructors
RenderTexture

Creates a new RenderTexture object.

Functions
Create

Actually creates the RenderTexture.

Release

Releases the RenderTexture.

IsCreated

Is the render texture actually created?

SetGlobalShaderProperty

Assigns this RenderTexture as a global shader property named propertyName.

SetBorderColor

Sets the border color for this render texture.

Class Variables
active

The active render texture.

Class Functions
GetTemporary

Allocate a temporary render texture.

ReleaseTemporary

Release a temporary texture allocated with GetTemporary.

Inherited members
Inherited Variables
width

Width of the texture in pixels (Read Only)

height

Height of the texture in pixels (Read Only)

filterMode

Filtering mode of the texture.

anisoLevel

Anisotropic filtering level of the texture.

wrapMode

Wrap mode (Repeat or Clamp) of the texture.

mipMapBias

Mip map bias of the texture.

name

The name of the object.

hideFlags

Should the object be hidden, saved with the scene or modifyable by the user?

Inherited Functions
GetInstanceID

Returns the instance id of the object.

Inherited Class Functions
operator bool

Does the object exist?

Instantiate

Clones the object original and returns the clone.

Destroy

Removes a gameobject, component or asset.

DestroyImmediate

Destroys the object obj immediately. It is strongly recommended to use Destroy instead.

FindObjectsOfType

Returns a list of all active loaded objects of Type type.

FindObjectOfType

Returns the first active loaded object of Type type.

operator ==

Compares if two objects refer to the same

operator !=

Compares if two objects refer to a different object

DontDestroyOnLoad

Makes the object target not be destroyed automatically when loading a new scene.
