Hi. I want to make my facade rotation degree can be change by a point attractor similar like in this video [https://youtu.be/1yQfzldvFno?si=IE-uxt02n5R5YU9O](https://youtu.be/1yQfzldvFno?si=IE-uxt02n5R5YU9O), then I will calculate sDA and ASE based on the sun attractor, but I dont know what to do. Can anyone help me?
