AnimGraphNode_SkeletalControlBase is returning nullptr for in UE 4.20
The above crash states LowLevelFatalError on skeletalControlBase.h at line 164 at the GetNode() pure virtual function.
This problem never happened in my same plugin project in 4.19,4.18 and so on.
There is no compilation error in visual studio apart from some errors such as "generated files not found" or "source files not found". While the custom animgraphnode compiles , the moment i try to spawn a node in any animation blueprint , it crashes every time , giving the posted stack trace starting from the GetNode() function.
This problem is also easily reproducible in a minimal class file deriving from AnimGraphNode_SkeletalControlBase.
Example almost blank starter code to reproduce the crash:
The virtual function GetNode() inside for some reason is always returning nullptr from my experimentation. I believe this is a bug introduced in 4.20 and i hope someone from epic can shed some light on this.
I'm struggling with the same issue, same fatal error in call stack. I've reset Windows 10, reinstalled VS 2017, Epic Games Launcher, then added a new engine 4.20.2, though to note I did all this in response to same behavior in 4.19.2, then adding 4.20.1, so that's one thing different here, problem prior to 4.20. One last thing I introduced with this most recent clean slate attempt was to isolate against a corrupted project file, restored from a backup that was stable at the time of backup. I'm out of ideas. Thanks for ideas!
