I made a post in another topic (
http://nutcracker123.com/forum/index.php?topic=2451.msg15069#msg15069) about an issue I was having with a vertical matrix and it displaying correctly in the sequencer. I have since discovered the cause of it and even though I wrote up the issue under that topic I want to put it here as well so that it can be properly tracked as a bug. The issue isn't just for the vertical matrix model but I'm assuming all models.
When you first go into the Dimming Curves panel the values are blank (see attachment). I believe that these values should be filled in defaults (0 perhaps?). That's the first problem. Of course if someone is going to be setting those values then it doesn't really matter. It becomes a problem though when you just enter the panel, don't change any values and then you click Cancel. Even though you click Cancel it still ends up saving the <dimmingCurve> element in the XML with blank values. This is what caused the issue that I was seeing in the sequencer. As soon as I removed the <dimmingCurve> element from the XML everything worked as expected.
In summary, I see 2 things that need to be fixed here:
1. Dimming Curve panel values should be initialized.
2. Dimming Curve panel values should be validated before saving to the XML.
