I am new to Xlights/Nutcracker this year and could apparently use some help setting up my channels/models. I was using HLS for the past 2 years and am planning to switch to pixels this year. I have been reviewing some tutorials and the user manual and just when I thought all things were going good I seem to have some over lap of channels. I thought I could set up sequentially and then use the start channel "end of model X". However this seems to have gotten me into some trouble. I created all my elements and display groups, tried to start a sequence and I am getting some overlap. So, I went back to the Layout tab>selected overlap check enabled and it highlights issues. However, I cannot seem to find/remedy my issues.I also received an error: could not calculate start channels for models...... Any help greatly appreciated.
