The following properties display in the Decal Types dialog when you create or modify a decal type. See Creating a Decal Type.
| Property | Description |
|---|---|
| Image File | Image 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 GUID-1052854D-7286-4806-861C-9D2DD1416ADA.htm#WS1A9193826455F5FF-6D855556117C4584E54-1FE8. |
| Brightness | Perception 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. |
| Reflectivity | Measurement 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. |
| Transparency | Measurement of how much light passes through the decal. Enter a value between 0 (completely opaque) and 1 (completely transparent). |
| Finish | Texture 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 Pattern | Bump 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 Amount | Relative 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-outs | Shapes 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. |
