Aysberg:
I was able to get the demo running, by copying the files into a new empty project created by the compiled editor like @DarknessFX wrote.
Compiling the Editor works for me by adding at least the following two lines to the UE4Editor.Target.cs. In my “demo” test build I added all the lines from DarknessFX post #446 .
bCompileChaos = true;
Tested with 4.25/4.25.1 in VS17 and VS19.
PS I have the same performance and moving obejcts problems stated by @BaronS_88
The first building worked for me, the second is marked as “Out of Order - The ‘Cached Simulation’ feature is currently being refactored.”".
I’m having the exact same issue I hope the professors build source has those problems fixed. Because I have tried building from source too, and ended up with the same issues.
