The information regarding needing the CMS installed is to allow the newer users who don't understand or know the tools, have the ability to see results quickly. If we said to everyone that the CMS is not needed, then someone new would get lost trying to run the RTR scenes.

 

Can you use it without? Sure, is it perfect without? No. Thus the recomendation to have it running. Remember we are messaging to those with not as much experience as you guys. And I don't think that is a bad thing (My opinion).
