intensity control

Should not the Intensity of the fixture in DyLos engine control the Intensity of RGB with intensity?
I used it over new years eve and it was great but notice I had to go to the Fixture them self and bring up the intensity of those type of fixture to make it work. We had Color Rail Irc in 26 Channel mode, R2 Wash in 33 channel mode, and 3D Vision panels. The 3D Vision work but the Color Rail and R2 I had to bring the Intensity of those fixture to make them work.
