I saw in someone's video, I cant remember which one now, they had made a moving spotlight across their whole display. From what I understand it was made in Xlights, and from another forum I saw where someone else asked about it. They reply was to use the balls effect and use location instead of strings. I have looked and the only thing I can find close is the effect called circles, however, maybe I need to read more in the manual, but can anyone elaborate for me about using location instead of strings. So far I have not been able to find it. Thanks!
