I have a new prop on in my display this year I working on. It my house outline, 33 pixels each side, across the top is 88 pixels for a total of 154. I was using the single strand effect on it. When I select in chase types' from middle" with the layer setting on single strand, it does not expand from the middle of the top section, it expands from almost the far side of the top strand. By the way it is wired as a single string, with data on the left side and power injection top right, between the top and right side. What I am looking for is to expand from the top middle and go down the sides, now it expands from near right side goes down the right side, but the left side moves up not down as expected. I hope this made since, if not I will send the files which I think are the rgb effects and the network files. they are on the show computer now. Thanks Charlie J.
