In game I use the network GUI.
I can host and play fine.
However when I host and then click stop, (DISPLAY 1 : No Camera’s Rendering comes up) and try hosting again it would appear my main camera is gone and errors occur trying to instance a camera that’s not there… How can I fix this? and how hard is it to write my own gui too?
Remove any kind of networking components from the camera. Wrapping the the network manager GUI would not be trouble but getting all those players ready to start game is going to be lots of trial and error.
