Ok… so this worked for me:
- Comment out BlueprintGraph & AnimGraph from PrivateDependencyModuleNames.
- Build solution file via right-click/batch file.
- Uncomment BlueprintGraph & AnimGraph from PrivateDependencyModuleNames.
- Open solution file.
- Compile/debug.
Editor loads.
PIE / Standalone work.
Since it includes AnimGraph module during compile, custom AnimGraphNodes works.
I don’t like it, but its a solution.
