Modify default light settings?

The command SetMobility takes

  • the namespace EComponentMobility
  • enum called Type
  • InMobility is the variable name of the passed enum

if default values work in this case it would be:

in light.h

void SetMobility(EComponentMobility::Type InMobility = EComponentMobility::Type::Movable);

Though if you are only learning c++ then I would advise at least making a backup of the header before any changes.
