I have 16 X 50 strings for my mega tree. How do I get the xlights to do a zig zag on the preview window?
If you have 16 strings, and string 1 starts from the bottom, 2 from the top, 3 from the bottom etc , in that case, make your tree model so that the strings are 2x the actual length and then configure the strings to have 2 strands per string. So, the model is 8 strings of 100 with 2 strands.
