KTM X-Bow or open top cars are best for this track. Ramps don't have a collision mesh unfortunately. From the top of the Tool Cabinet to the end of the Milling Table and back is the intended lap. Pit Boxes 0-7 are on the tool cabinet. Pit Boxes 8-15 are on the floor. A race with 8 cars total would almost work. There is one secret passage and two cartoon characters hiding.This was my first track with the main intention of getting a file from SolidWorks into VR. Thanks to everyone who post free CAD files and detailed tutorials online!3D Model References:Arduino Uno – ?Step Clamps – McMaster Carr
