I seem to have a problem, my game is in FE and whenever I check the PlayerGui, there is nothing in there from the StarterGui.
Can someone help me and tell me how to clone the contents into the player's PlayerGui when they spawn?
The contents of StarterGui get cloned to the local PlayerGui. This means that each user will have the contents of StarterGui in their PlayerGui.
However, this means that the server cannot access the PlayerGui. FE prevents this. The contents of StarterGui get cloned into everybody's PlayerGui, but client-side.
You'll need to use RemoteFunctions to access the data, if wanted.
