Thanks for the quick response, it pointed me in the right direction
Sorry, for being so vague, I had never used Unity before so it was hard to describe my problem. I was not even aware of the console in Unity. I believe my trouble was that I was not using the Pro version, Registered for the 30 demo and was able to get it up and running. Also downloaded Simple Server and Client, that have been great for troubleshooting.
I now have Max, Quartz, and Unity working nicely together. I have no experience using FreeFrame, but will be working on that next.
Syphon is very exciting, I feel like I finally have the tools to compose video and audio, the way that I want to.
