Changing the Number of Wheels on Flexible Tracks
To add or remove a new wheel definition to the wheel list of a flexible track, follow these instructions:
From the Explorer panel, click on the vehicle Flexible track extension.
In the Properties panel, under the Parameters header, expand Left Track.
Expand the Wheel Item List header and adjust the Size parameter to add or remove wheels.
Repeat steps 2 and 3 for the Right Track parameter.
Note When changing the value of the Wheel Item List Size field, make sure that the values of the Wheel Attachment field are not zero nor equal to its related Wheel Position. You must add an offset between these two positions otherwise the tracks will disappear.
