So I wasted some time trying to debug incorrect values until I actually logged them out and realised they were correct. Should I treat that debug panel as a filthy liar and just log everything I need to know or have I misconfigured my VS (2017) install?
For context, I had an FVector showing -nan and silly massive numbers.
You need to be running in debug game or debug editor for the configuration (I don’t remember which one). You should also download the pdb’s for the engine unless you are building it yourself.
