    The following properties display in the Decal Types dialog when you create or modify a decal type. See Creating a Decal Type.

    PropertyDescription
    Image FileImage file to display for the decal. Click (Browse) to navigate to the file. Revit supports image files of the following types: BMP, JPG, JPEG, and PNG. See Best Practice for Storing Image Files.
    BrightnessPerception of the luminance of the decal. Brightness is a multiplier, so a value of 1.0 makes no change. If you specify 0.5, its brightness is reduced by half.
    ReflectivityMeasurement of how much light the decal reflects from its surface. Enter a value between 0 (no reflections) and 1 (maximum reflections). See Transparency and Translucency.
    TransparencyMeasurement of how much light passes through the decal. Enter a value between 0 (completely opaque) and 1 (completely transparent).
    FinishTexture of the decal surface.
    Luminance (cd/m^2)Light emitted by the surface, measured in candelas per square meter. Select a predefined value, or select Custom to enter a value.
    Bump PatternBump pattern (additional texture) to use on the decal surface. See Specifying an Image File for a Render Appearance. This texture is layered on top of any texture already applied to the surface on which the decal is placed. For example, if you place a decal on a brick wall, the texture of the brick wall affects the decal, in addition to the decal texture specified here.
    Bump AmountRelative amplitude of the bumps. Enter 0 to make the surface flat. Enter higher decimal values (up to 1.0) to increase the depth of the surface irregularities.
    Cut-outsShapes cut into the surface of the decal. Select a shape, or select Custom to define cut-outs using an image. See Specifying an Image File for a Render Appearance.
