Using Different Media for the Displacement Source

You can specify different media as the displacement source. Do this to apply a custom matte, or alpha, as a displacement map instead of using one media for both the texture and displacement.

To use another media as the displacement source for a surface of Media1:

1. In Action, click Media to access the Media menu.
2. Select a media from the Media list, or click <new media> and Add to return to the EditDesk to add new media.
   NoteIf Auto Image or Auto DVE is selected in the Auto Image option box in the Setup menu, an image node and axis, or a DVE Layer Object node is created when adding new media. These nodes are not needed for displacement mapping, and can be hidden or deleted.
3. In the schematic, select the surface to which you want to apply displacement mapping.

   Notice that in Schematic view, the number and symbol next to the name of the selected surface node is (1)(-). (1) indicates the media for the surface is Media1. (-) indicates the default media is used as the displacement source. The default media is the media applied to the surface (also Media1).

4. In the Media menu, click Displace.

   In Schematic view, the two numbers next to the name of the selected surface node change to (1)(2), for example. (2) indicates Media2 is used as the displacement source.

5. To reset this override, select Node from the Reset box, click Reset, and then Confirm.

   NoteDisplacement mapping uses the media's matte clip, so make sure that you turn the matte on or off to get the right effect.
