Handy tips thanks.
May have a running version (fingers crossed) kept getting external resource errors. Tried lots of things but what appeared to work was re-naming my project folder?! The project was a copy of my 4.6 version so renamed both project folders and it broke a couple of things but it did look as though the projects had gotten tangled!??
Thinking of adding different target FPS’s 30 / 60 / 90 / 120 but it’s getting there!
Does going to the released source and compiling and building the engine help with bugs, as in does Unreal release to source builds with bug fixes before they become preview builds?
