An expanded set of BlendMode Material Functions for Unreal Engine. These are useful for adjusting the colors and mood of a scene via post process materials, for creating interesting translucent effects, and for blending together textures or intermediate results in a material graph to create interesting effects or refine the final color on a surface.

What's Included

• 50 total blend functions

  • 36 new blend functions, each of which includes an Opacity parameter that allows the user to control the intensity of each effect (similar to how the Opacity slider on an adjustment layer works in most image editing applications--the value should generally be in the 0..1 range).

    • Some functions have additional inputs. These all have usable default values and descriptions of use documented in the nodes, so simply hovering your mouse over the input pin should provide an explanation of what the additional parameters do, what valid values are, etc.

  • Wrappers around the 14 built-in blend functions to include an Opacity parameter and allow them to be used in the same way as the new ones.

• An example material allowing you to quickly flip through the different blend functions in a (provided) material instance to preview the results of each.

• An example material function which combines the functionality of all 50 functions into a single node for easy testing in a material graph.

• A couple of additional utility material functions for color space conversion (required for the implementation of some blend functions, but might be useful for other projects).

In the material editor, all of the included functions can be found under NB - Blends in the function library.
