In Rift Rally, the Chameleon will enhance your world by adding in digital content, such as trees lining the side of the track or interactive objects used for challenge objectives in the Campaign.
If digital content appears to slide around or act unstable, such as the track or gate moving in-game, it may be that your Rift Gates have moved too far from their original positions set during track setup.
In this scenario, either return the Rift Gates to their original locations, or rebuild your track to ensure that the game is tracking the correct location.
Another possible cause for shifting digital objects is extremely bumpy terrain or flooring transitions. Sudden or drastic bounces may temporarily cause digital content to move around. Although this should resolve itself fairly quickly, you may want to avoid such terrain to ensure maximum stability.
Finally, note that Rift Rally only functions using one set of gates at a time. If additional numbered gates from other Rift Rally games are placed anywhere in the view of the Chameleon, it can cause track instability. Ensure that only one set of gates number 1-4 are in use at a time.
