yes, I knew that they are stored in degrees, but was wondering if they are already Euler angles, or some other angles that are maybe interdependent. Degrees does not have to be Euler angles, but can be some other convention.
Suspicious is, that the FRotator::Euler documentation seems to say that whatever is stored as angles (in degrees) in a rotator gets converted to Euler angles (in degrees) with FRotator::Euler.
is there some documentation about angular conventions in UE4 or is it ‘feel free to look up the source code’?
