I have tried several different methods of building RGB arches in LOR Visualizer, including trying to use the arch wizard, trying to use the CCR arch wizard and cutting/pasting my non-CCR cells into them, then finally trying to manually build an arch with the "draw single bulbs" wizard. The "draw single bulbs" worked really great until I got up to bulb #15 or so, then it just stopped working correctly. Up to that point, using the drop downs to assign the individiual fixtures' properties was working great, but then it just stopped working--it's like it no longer understood I was trying to assign RGB channels. I can still type in everything manually (name, universe, channel # within the universe, etc), but that is really really time consuming. I even tried to use some "outside of LOR" files but I couldn't really figure out how to pull them over into LOR at all. Any help anyone can provide would be GREATLY appreciated!! I was really hoping to use LOR VIZ when initially sequencing four arches I will be installing this year, but it is not looking good for the home team!!!
