I'm Lost... Trying to build set up simple multi cell LED

So I have been really lost trying to build a simple multi-cell LED fixture I have watched videos and looked on the web and manuals but have been unable to find anything that clearly shows how to do it for MA3 seem like the fixture builder only allows one set of RGB attributes to function.

I tried to look at pre-built fixtures like nexus led but that revealed nothing on what I am missing in the builder..

Does anyone have a resource that clearly shows how to do this?

Thank you in Advance!

Update so I finally figured out how to get the multi-instance to function, and I have full fixture functions, however, my 3d model in Ma 3 shows the individual cells it does not "output" light in the 3d.
