tfRoad generates a procedural road based on the path, with built-in cloning for adding roadside structures such as street lamps, traffic lights, steel barricades or trees, to make the road more realistic.

tfRoad uses the spline path to create the road geometry.

Object tab

Spline

Drag the spline into the Spline link field to create your road geometry.

Here a Text Spline has been dropped into the Spline link field.

You can also use an xpTrail generator to create road geometry in an interesting way, as part of an xpSystem.

Rail

Drop a spline into this link field to precisely control the banking of the road, which is essential for realistic-looking curves.

Note: tfRoad assumes that the road profile’s Y-axis will point towards a rail spline, as illustrated below.

Here a Helix spline (on the left) is driving the generation of road, on the right, without Autobanking or a rail spline.
