I finished putting together a mega tree of 16 string of 50 pixels each and I'm using an E682 san devices with nutcraker 4, everything is fine the problem is that the colors that come out in the preview window are not the same colors in the mega tree , For example e used the Strobe Light effect only with white color and in the preview window is correct but in the physical tree some red and blue dots come out. I want to thank you for the help in this reason and happy day thanksgiving to all.
