Blends

A Blend is a type of function that performs mathematical calculations in the color information of a texture so that one texture can blend into another in a particular manner.

Blends will always have a Base and a Blend input, both of which are Vector3. These will each take in a texture and the two will be blended in some way. The manner in which the blend takes place depends on the type of blend function used.

Blend Functions

Below is a list of all of the blend material functions.

Blend_ColorBurn

Blend_ColorBurn blends the textures in such a way that the darker the Blend color the more of that color will be used in the final result. If the Blend color is white, no change takes place.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Color Burn



	Base	Blend	Result

Blend_ColorDodge

Blend_ColorDodge lightens the result by inverting the Base color and dividing it by the Blend color.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Color Dodge



	Base	Blend	Result

Blend_Darken

Blend_Darken works by choosing the darker value for each pixel of the Base and Blend colors. A white Blend color does not produce a change.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Darken



	Base	Blend	Result

Blend_Difference

Blend_Difference creates a sort of inversion-style effect by subtracting the Base from the Blend and then taking the absolute value of the result.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Difference



	Base	Blend	Result

Blend_Exclusion

Blend_Exclusion halves both the Base and Blend textures, combines them, and then does a partial inversion on the result.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Exclusion



	Base	Blend	Result

Blend_HardLight

Like a harsher version of Blend_Overlay, Blend_HardLight will either screen or multiply the Base and Blend together. The function does a comparison on the Blend color such that wherever the Blend is brighter than 50% gray, the Base and Blend will be combined via a Screen operation. If the Blend is darker than 50% gray, the Base will be multiplied by the Blend as in the Multiply function. The contrast of the final result is then boosted for a harsh output.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Hard Light



	Base	Blend	Result

Blend_Lighten

Blend_Lighten compares each pixel of the Base and Blend colors and returns the brighter result.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Lighten



	Base	Blend	Result

Blend_LinearBurn

Blend_LinearBurn adds Base color to the Blend color and then subtracts 1 from the result.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Linear Burn



	Base	Blend	Result

Blend_LinearDodge

Blend_LinearDodge adds the Base color to the Blend color.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Linear Dodge



	Base	Blend	Result

Blend_LinearLight

Blend_LinearLight is a linear version of Blend_Overlay, providing harsher results. The function does a comparison on the Blend color such that wherever the Blend is brighter than 50% gray, the Base and Blend will be combined via a Screen operation. If the Blend is darker than 50% gray, the Base will be multiplied by the Blend as in the Multiply function.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Linear Light



	Base	Blend	Result

Blend_Overlay

Blend_Overlay will either screen or multiply the Base and Blend together. The function does a comparison on the Blend color such that wherever the Blend is brighter than 50% gray, the Base and Blend will be combined via a Screen operation. If the Blend is darker than 50% gray, the Base will be multiplied by the Blend as in the Multiply function.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Overlay



	Base	Blend	Result

Blend_PinLight

Like Blend_Overlay, Blend_PinLight will either lighten or darken the Base and Blend together. The function does a comparison on the Blend color such that wherever the Blend is brighter than 50% gray, the Base and Blend will be combined via a Screen operation. If the Blend is darker than 50% gray, the Base will be multiplied by the Blend as in the Multiply function. The contrast is softened, making this a less harsh version of Overlay.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Pin Light



	Base	Blend	Result

Blend_Screen

Blend_Screen lightens the Base by the Blend color. It does this by doing a "one minus" on both colors, multiplying them together, and taking a one-minus of the result.


Item	Description
Inputs
Base (Vector3)	The base, or original texture that will be blended with the Blend texture in some way.
Blend (Vector3)	The blend texture, which is combined with the base in some way based on the type of blend operation taking place.

Screen



	Base	Blend	Result

Blend_SoftLight

Blend_SoftLight is a softer version of Overlay. The function does a comparison on the Blend color such that wherever the Blend is brighter than 50% gray, the Base and Blend will be combined via a Screen operation. If the Blend is darker than 50% gray, the Base will be multiplied by the Blend as in the Multiply function. The contrast is softened, making this a less harsh version of Overlay.
