Overlay Parameters
GenesisII's Overlay rendering mode draws the landscape surface with images overlayed (or draped) onto the surface. This editor controls the images used and the way that they are drawn. Images are drawn stretch so that the corner of the image is mapped to the corner of the map.

Overlay Images

Overlay list: List the images available. Click Add to add an image. Select an image to edit it's properties. Drawing for any particular image can be turned on or off by changing the check box status.

Image Details

• Name: An arbitrary name assigned to each image. Does not have to be unique - although this is recommended.
• Source File: A bmp file containing the overlay image.
• Set Overlay Directory: Sets directory path for overlay bitmaps.
• Transparency Mode: GenesisII can draw an image with either the whole image layer transparent, or just a particular color. Select which mode is required using the drop down list. Note that each image layer can have different characteristics, but the first layer is always drawn with the full layer at 100% opacity.
• Transparency: Degree of transparency of the image layer. Ranges from 100% for total transparency to 0% for total opacity.
• Transparent Color: In single transparent color mode this is used to select the color which will be drawn transparently.
