Firstly Merry Christmas/Happy festive season to all at BIS.
Currently it is very difficult to get Say3D to work on all clients in a MP game unless called via a trigger.
What we ideally need is a native command in Arma3 like the CBA option call CBA_fnc_globalSay3d which works faultlessly if called via most methods.
We also need is the ability to stop say3D without having to delete the attached object.
