RavenWorks
  1. Make a world in the Unity editor
  2. Go to "build & test your world"
  3. Set it to Windows, 2 clients, force non-VR
  4. Build, and wait for the two windows to be ready
  5. Walk one of the windows so it's staring the other one in the eye
  6. In one window, the two users are the same height, and they look each other in the eye by staring straight forward. In the other window, one user is at least a head taller than the other, and is staring out into space.
The problem isn't so much that the test users aren't the same height (if anything, that could be handy for testing) but rather that their heights AREN'T CONSISTENT in the two windows; one window has them the SAME height, the other has them as DIFFERENT heights. This confuses several things when trying to test synced Udon things.
This is happening for me in SDK 3.7.6 and 3.8.0.
