The Prop Point Tool is used for placing individual props in the scene or connecting them to other props.
To place a prop, select the prop in the Asset Browser and right-click in the 3D scene. The prop should appear in the scene and be positioned on whatever surface the mouse cursor is over. In this way, props are automatically positioned on the terrain surface. If the Align Normal option is set for the prop, it will also rotate itself to align with the surface it is placed on.
If any of the Rotation Variance or Scale Variance attributes are set for the prop, then these properties will be randomized when the prop is placed. For example, for trees and plants, it is very useful to set the Z-value of the Rotation Variance to 360 degrees, causing the prop to be randomly rotated around the vertical axis and making it easier to reuse the same plant models in multiple places without the repetition being obvious. In addition, setting the Uniform Scale Variance to 0.1 will cause a 10% randomization in the overall size of the plant.
See Point Editing.
This operation works from any tool. Once done, RoadRunner automatically enters the appropriate tool and selects the object for further editing.
Simple props can be combined and attached to one another to form more complex groups of attached props. For example, a custom traffic signal can be constructed by combining a post, a mast, and multiple signal heads.
Click the Prop Point Tool button.
Click and drag a compatible asset directly from the Library Browser onto the green prop attachment curve of another prop in the scene.
For more information about prop attachment curves, see Prop Attachment Curves.
A group of connected props can be saved as an asset. This allows a complex group of attached objects to be quickly re-instantiated in the scene.
For more details, see Prop Assembly Assets.
