Road Generator

WARNING

Because the road generator plays a crucial role in the mapping process, this chapter has been added to the basic section to introduce the most fundamental usage of the road generator.

The content of this chapter has a decisive impact on mapping quality and efficiency. Please be sure to read it carefully and practice a lot. Do not skip this chapter!

The roads, rails, wood boards, and tubes in Ballex² are all made with the road generator.

Creating a Road Generator

Create → Road Generator

In this Start section, only common usages and frequently used parameters will be explained. The most critical parameters are:

• Generator Algorithm
• Length
• Width
• End Width
• Segments
• Bend
• OffsetsGenerator Algorithm = Rail

TIP

• The Custom Vertices road generator will be detailed in the Advanced section.
• The Custom Script road generator will be detailed in the Script section.

Straight Road

• Select Generator Algorithm as Road.
• Set the Length.
• To create a concave road, set Concave and End Concave (recommended value is 0.1).
• To create a wide road, set Width and End Width (recommended value is 3).
• To create a sloped road, set End Height and check Precise UV Length.

TIP

Length is the projected length onto the horizontal plane and is an independent parameter from End Height.

If both ends are obstructed by other objects, you can uncheck Create Caps to improve performance.

Straight Wood Board

• Select Generator Algorithm as Wood Board.
• Set the Length.
• To create a wide wood board, set Width (recommended value is 2).
• To create a sloped wood board, set End Height and check Precise UV Length.

Straight Rail

• Select Generator Algorithm as Rail.
• Set the Length.
• To change the dual-rail gauge, set the Offsets (not recommended to modify).
• To create a monorail, set the Offsets count to 1 with a value of (0, 0).
• To create a sloped rail, rotate the rail and connect it with matching curved arc rails.

Straight Tube

• Select Generator Algorithm as Tube.
• Set the Length.
• To increase the tube's outer diameter, set Radius and End Radius (recommended value is 0.75).
• To change the cross-section's central angle, set Slice (recommended value is (0, 180)).

Arc

• Calculate the corresponding Length based on the desired radius and central angle.
• Set Bend Y to the angle between the end direction and the start direction, in degrees. A right turn is positive, a left turn is negative.
• Set the Segments appropriately based on the angle above (recommended value is Yaw Angle / 7.5, rounded up).

Spiral

• Set End Height to the height difference between the end and the start.
• Other settings are the same as for an Arc.

Roll

• Set Bend X to the angle between the end direction and the start direction, in degrees. Pushing down is positive, pulling up is negative.
• Other settings are the same as for an Arc.

Twist

• Set Bend Z to the angle between the end direction and the start direction, in degrees. A counter-clockwise twist is positive, a clockwise twist is negative.
• Other settings are the same as for an Arc.

WARNING

To avoid strange results:

• Do not set both End Height and Bend X parameters at the same time.
• Do not set both Bend X and Bend Y parameters at the same time.

Corner

• Select Generator Algorithm as Corner.
• Set the Size corresponding to the road width.
• Click to modify the texture styles of the edges and corners.
