The visible relief is called the composite relief. It is made from a stack of one or more visible relief layers. You can significantly affect how the composite relief takes shape by changing a relief layer's combine mode. ArtCAM starts with the layer at the bottom of the stack, then moves upwards, applying the combine mode for each visible layer.
To set a relief layer's combine mode:
- Display the 3D view.
- Ensure the relief layer is visible.
Note: The combine mode icon in the Project Tree is unavailable when a relief layer is hidden.
- In the Project Tree, select a layer in the Front Relief or Back Relief layer stack to display its panel below the splitter bar.
- Select an option from the Combine Mode list to specify how you want to combine the relief layer's content with each visible layer below. Select:
Add to add the relief layer's content to the visible layers below in the stack.
Subtract to subtract the relief layer's content from the visible layers below in the stack.
Merge High to merge the relief layer's content with the visible layers below in the stack, so that only the highest points remain.
Merge Low to merge the relief layer's content with the visible layers below in the stack, so that only the lowest points remain.
Multiply to multiply the height of the relief layer's points by the coincident points on the visible layers below in the stack.
Note: If you create a relief layer, Add is selected by default.
Note: When you import relief clipart, you can choose the layer's combine mode.
Tip: To create a feasible composite relief, a relief layer with the
Multiply
combine mode applied should have a maximum Z height of between 0 and 1.
