Description

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.

One typical usage of render textures is setting them as the "target texture" property of a Camera (Camera.targetTexture), this will make a camera render into a texture instead of rendering to the screen.

Another use case is manually implementing various rendering effects, for example Image Effects. There you often get temporary short-lived render textures (GetTemporary and ReleaseTemporary functions), and manually render objects into them (see Graphics.DrawMeshNow and Graphics.Blit).

Keep in mind that render texture contents can become "lost" on certain events, like loading a new level, system going to a screensaver mode, in and out of fullscreen and so on. When that happens, your existing render textures will become "not yet created" again, you can check for that with IsCreated function.

See Also: Camera.targetTexture.

Static Variables

activeCurrently active render texture.

Variables

antiAliasingThe antialiasing level for the RenderTexture.
colorBufferColor buffer of the render texture (Read Only).
depthThe precision of the render texture's depth buffer in bits (0, 16, 24 are supported).
depthBufferDepth/stencil buffer of the render texture (Read Only).
enableRandomWriteEnable DX11 random access write into this render texture.
formatThe color format of the render texture.
generateMipsShould mipmap levels be generated automatically?
heightThe height of the render texture in pixels.
isCubemapIf enabled, this Render Texture will be used as a Cubemap.
isVolumeIf enabled, this Render Texture will be used as a Texture3D.
sRGBDoes this render texture use sRGB read / write (Read Only).
useMipMapUse mipmaps on a render texture?
volumeDepthVolume extent of a 3D render texture.

Inherited members

Variables

hideFlagsShould the object be hidden, saved with the scene or modifiable by the user?
nameThe name of the object.

GetNativeTexturePtrRetrieve native ('hardware') pointer to a texture.

Static Functions

DestroyRemoves a gameobject, component or asset.
