In addition to the last blog i would like to talk about bridge and tunnel styles.
Once a road style is selected for editing you may enter the “Street Type” for this style to be set. Depending on the three options apart from roadways a specific box appears in the upper right corner of the Style Editor to select bridge & tunnel.
The roadway has been described already. Now we want to take a quick look at the other two options.
Starting with the Bridges, you can see some Bridge related settings. The “Bottom Surface Category”, “Outer Surface Category” and the “Pylon Surface Category” are materials to be defined in the “Default Material Group” (see Older Post).
The “Bottom Surface” describes the surface from underneath the bridge; “Outer Surface” covers the vertical outer side walls and the “Pylon Surface” maps a material to all of the pylons of the bridge.
The “Thickness” sets the meters between the road surface and the bottom of the bridge body.
ACTION: Enter some higher and lower values and check the preview in the style editor.
Last but not least you may specify the pylon size and the spacing between them. Check the values and position and size the pylons as you think the look best.
Road Styles can be designed as brides as well as tunnels. Even the boulevard style can be turned into a tunnel but I doubt that palm trees in a tunnel make sense, but you never know what sustainable design may produce.
The “Tunnel Settings” provide four categories to texture the tunnel cube. A material can be set for the top celling (Top Surface Category). This is important when a tunnel starts outside a terrain you would want to texture the top cover of the tunnel.
The bottom celling is textured under “Bottom Surface Category”, which you actually see in the tunnel.
“Outer and Inner Surface Category” describe the inner and outer walls of the tunnel cube.
The “Height” defines the distance from the Roadway (or lowest track) up to the top surface and the “Wall Thickness” is the depth of the tunnel walls including the tunnel cover.
Have a good one!
