Sign Assets

Define standard and custom street signs


Sign Asset sample

Sign Assets are used to create and edit standard and custom street signs.


RoadRunner has tools for quickly creating both basic and complex road signs. These signs can be created and stored in the project assets, and then placed throughout the scene in 3D. A basic sign is a sign that is built from a single image file (bitmap or vector graphic), such as a stop or yield sign. A complex sign can have multiple elements, such as text and graphics, such as a custom freeway guide sign. Both basic and complex signs can be created as assets in the asset library and then instanced in the scene as props.

Create Basic Sign Asset from Single Bitmap or Vector Image

  1. Click in the Asset Browser to select the destination directory in which to import the sign.

  2. Drag the bitmap file (JPG, PNG, or BMP) or vector graphic file (SVG) from a file browser into the Asset Browser. This action copies the actual file into the project assets. Once the image is in the project assets, RoadRunner automatically generates an icon for the image.

  3. Right-click the asset icon and select the Default Type > Sign menu option. This treats the image file as a sign asset type and is necessary because images can be used as other asset types as well.

Create Complex Sign Asset with Custom Text and Graphics

To create a complex sign asset with custom text, graphics, and so on, follow these steps:

  1. Click in the Asset Browser to select the destination directory in which to import the sign.

  2. Right-click in the Asset Browser and select the New > Sign menu option. This selection creates a new sign asset that can be further customized with the Sign Tool.
