Multi Color LED Beam Fixture how to

[eedetail]

I have been rebuilding my base show and thought I would play with 3d for a while.
I wanted to simulate a multibeam led fixture, like the Aggressor.
I created several fixtures in setup with a single dimmer channel, each with a different color;
5 degree beam angle and 60w led.
(Use one color per channel)
In setup, have several clones of each fixture.
For the fixture that I control with DMX, i used channel 18, for the other two colors I used
"dummy" channels - 510 and 511, figuring I wouldnt need those channels for real.
In 3d view, place all fixtures at the same place, but with different beam direction.
Attached graphic is the result.
