I am working on a show with multiple LED Fixtures, and had to create my own Fixture Library. 
  
For the LED's its pretty easy, one Virtual Channel, and then RGB for the Colours 
  
a couple of them have a 4th channel for their mode. 
  
All Simple Stuff, however when I load my Fixtures into the Ill-500, then for each fixture the colours show up under the colour window, but there is no Overall Brightness control. Which will make plotting rather difficult. 
  
I have attached my Fixture Lib, Can Anyone give me a clue where i am going wrong.
