Images may be set to a specific color, or draped to a triangulation by importing both the image and associated georeference file.

  1. Select a layer in the Layers panel.

  2. Click on the color selection dropdown to the right of the layer name.

  3. Click the Color tab.

  4. Click the color selection button to display the color palette and opacity level.

    1. Select the desired color and adjust its settings to your preference.

    2. View the resulting color in the Sample field.

    3. You can also enter numerical values for color hue (Hue), Saturation (Sat), Brightness (Bright), Transparency (Opacity) or specify a color number in the palette (#).

    4. Use the Make Web-Safe button to assign a web-safe color to the image.

    5. Tick the Use Dynamic Lighting checkbox if you want to use dynamic lighting. But note that this flag will cause the image to be of higher quality, which will slow down the planning process.
