Object tracking lighting changes

Why do lighting changes affect Wikitude object tracking performance in Unity when using Wikitude's object tracking - especially the size or scale we're dealing with (6-ft. tall statues). The color and amount of light seem to affect it. Is there a color threshold? If the color doesn't fall within a threshold it seems to disregard it as a target. Is there a way to expand the threshold so it's not so finicky with the colors?

Tracking is affected by the quality of the images captured by the camera. If the image is very over or underexposed, tracking might fail because all the features of the object are not recognizable anymore. Can you please post some screenshots from your app when tracking fails?

Best regards,
