I have 25 pixels each around windows and garage doors and I can't get the chase effect to go around in a circle. It lights up one side or the other (depending on your direction), goes across, then lights up the other side. I am using the same effect for eaves, and it is working. I am using the custom model for the window frame for both the windows and the garage.
Thanks
Edit: I haven't tested this yet, only in the preview window.
