Cross Fader

Outputs

Name	Type	Description
Texture Output	Texture	The fade between the two inputs the fader sits between.

Inputs

Name	Type	Description
Inputs	Texture	The textures to fade between, in order. Connecting to the list adds an input at the end.

Parameters

Name	Type	Description
Texture Type	Enum	The channels of the output texture.Choices: R (u8), RG (u8), RGBA (u8)
Texture Size	Vector 2 Int	The size of the output texture in pixels.
Fader Position	Float	Where the fader is. 0 is the first input, 1 the second, 2 the third, and a value in between fades between the two nearest.

Cross Fader dissolves from one texture to the next, like the fader on a video mixer. The inputs are a list, and the fader position walks along it. At a whole number the output is exactly that input, counting from 0 for the first. Halfway between two whole numbers the output is an even mix of the two inputs on either side. Every pixel is mixed on its own, so it is a plain dissolve with no wipe or motion.

One fader can therefore step through a whole set of textures. Drive the position with a Ramp to make a timed transition, or with a Counter smoothed by Smooth to cut and fade between scenes on a trigger. A position below 0 or past the last input is held at the end.

With no inputs the output is empty, and the output is also empty while either of the two inputs the fader sits between has no texture.
