Mixing Artnet-Universes

Hey all!

Years ago I had a setup (not Onyx) using two different machines serving the same Artnet-Universe. One PC was controlling RGB, the other one controlling Dim, Strobe and Movement. The Fixture on this, second PC had a gap where the RGB channels usually were located, the other one was filling this slots.

First question, is it possible with Onyx?

Second Question, can I manipulate the fixture in the Editor to erase the RGB-Channel’s and get such a gap? What would be the right setting for those Channel’s to be transparent?

Any help is appreciated.
