The 3D surface maps do support layer transparency.
To do this:
- Select one of the surface layers.
- In the Properties window, in the Material Color section, click the (...) button to the right of Upper.
- Change the Opacity value for the color(s) of the surface.
- Click OK and the opacity is applied to the layer.
To set the opacity of the color nodes in a script, use the ColorRGBA property of the ColorNodes object:
Dim ColorNodes As Object Set ColorNodes = ColorMap.ColorNodes ColorNodes.Item(1).ColorRGBA.Color = srfColorGreen ColorNodes.Item(1).ColorRGBA.Opacity = 33 ColorMap.ColorNodes = ColorNodes
