An update - I’m finding I have no shadows in perspective OR orthographic when I go in game, even though the shadows are there in the level. Could be some sort of side effect of having 4 players and 1 camera (all player controller view targets are set to the one camera).
I have no workaround yet - I’m just ignoring the graphical artifacts for now, hoping some sort of fix comes along that doesn’t affect the rest of the code.
