Bases: MaterialExpression

Material Expression Desaturation

C++ Source:

  • Module: Engine

  • File: MaterialExpressionDesaturation.h

Editor Properties: (see get_editor_property/set_editor_property)

  • desc (str): [Read-Write] A description that level designers can add (shows in the material editor UI).

  • luminance_factors (LinearColor): [Read-Write] Luminance factors for converting a color to greyscale.

    The default luminance factors values are now derived from the working color space. For uses cases outside scene rendering, users are responsible for updating these factors accordingly. For example, factors derived from an AP1 working color space would not be applicable to UI domain materials that remain in sRGB/Rec.709 and thus should instead use approximately [0.2126, 0.7152, 0.0722].

  • material_expression_editor_x (int32): [Read-Write]
