@Gaspar Potocnik I am running sACN and its a Mac.
@bbudzon I don't have boot camp on this machine but can look at getting that installed to test it out. I don't have a system on hand right now with any kind of decent internal graphics card either, I'm working on a show that is next week and the file is pretty big. I seem to have things working smoothly for now, the issues I was having seemed to possibly be file related. After several tries sending to vision from vw, I eventually get a file that works just fine. The files with issues also seem to have some kind of various issues with objects randomly missing, a stick of truss in one, a light fixture in another, etc. Just going back and sending to vision again from the same vw file without any modifications eventually gets me a vision file with all objects showing up correctly, and that isn't having the rendering problems
