Channel Shuffle

Outputs

Name	Type	Description
Texture Output	Texture	The assembled texture.

Inputs

Name	Type	Description
Texture Input A	Texture	The first source. Any input with nothing connected counts as black.
Texture Input B	Texture	The second source.
Texture Input C	Texture	The third source.
Texture Input D	Texture	The fourth source.

Parameters

Name	Type	Description
Output Format	Enum	Which input the output takes its size and type from, or Manual for the settings below.Choices: Copy Input A, Copy Input B, Copy Input C, Copy Input D, Manual
Texture Type	Enum	The channels of the output texture. Follows an input unless the output format is Manual.Choices: R (u8), RG (u8), RGBA (u8)
Texture Size	Vector 2 Int	The size of the output texture in pixels. Follows an input unless the output format is Manual.
Red Input	Int	Which input the red channel is taken from, counting from 0 for A to 3 for D.
Red Channel	Enum	Which channel of that input becomes red, or a fixed 0 or 1.Choices: Red, Green, Blue, Alpha, 0, 1
Green Input	Int	Which input the green channel is taken from, counting from 0 for A to 3 for D.
Green Channel	Enum	Which channel of that input becomes green, or a fixed 0 or 1.Choices: Red, Green, Blue, Alpha, 0, 1
Blue Input	Int	Which input the blue channel is taken from, counting from 0 for A to 3 for D.
Blue Channel	Enum	Which channel of that input becomes blue, or a fixed 0 or 1.Choices: Red, Green, Blue, Alpha, 0, 1
Alpha Input	Int	Which input the alpha channel is taken from, counting from 0 for A to 3 for D.
Alpha Channel	Enum	Which channel of that input becomes alpha, or a fixed 0 or 1.Choices: Red, Green, Blue, Alpha, 0, 1

Channel Shuffle takes the output texture apart into its four channels and says where each one comes from. For every output channel there are two choices: which of the four inputs to read, and which channel of that input to take. A channel can also be set to a fixed 0 or 1 instead of coming from an input.

That makes it the tool for moving channels between textures. Taking red, green and blue from one input and alpha from the red channel of another uses a gray texture as a transparency mask. Taking every channel from the red channel of one input spreads a single channel over the whole image. Setting alpha to 1 makes any texture fully opaque.

An input with nothing connected counts as black, so a channel taken from it is 0.
