Relief Macro |
This macro has two modes. One is to add shading to
an image with an alpha mask. For example, add shading to a Text operator.
To do this, use only one input, and keep the mode on Shading. The second
mode is to turn is to turn mode to Relief, and add a second background
image. The first image will create highlights and shading on the background
image.
