Graphics.Blit

static function Blit(source: Texture, dest: RenderTexture): void;

static void Blit(Texture source, RenderTexture dest);

static def Blit(source as Texture, dest as RenderTexture) as void

static function Blit(source: Texture, dest: RenderTexture, mat: Material, pass: int = -1): void;

static void Blit(Texture source, RenderTexture dest, Material mat, int pass = -1);

static def Blit(source as Texture, dest as RenderTexture, mat as Material, pass as int = -1) as void

static function Blit(source: Texture, mat: Material, pass: int = -1): void;

static void Blit(Texture source, Material mat, int pass = -1);

static def Blit(source as Texture, mat as Material, pass as int = -1) as void

Parameters

source	Source texture.
dest	Destination RenderTexture, or `null` to blit directly to screen.
mat	Material to use for copying. Material's shader could do some post-processing effect, for example.
pass	If -1 (default), draws all passes in the material. Otherwise, draws given pass only.

Description

Copies source texture into destination render texture.

This is mostly used for implementing image effects, and requires Unity Pro.

Blit sets dest to be active render texture, sets source as _MainTex property on the material, and draws a full-screen quad.
