In ConstraintDrives.cpp, SetAngularPositionDrive and SetAngularVelocityDrive do not use "InEnableTwistDrive" and instead assign "TwistDrive" to "InEnableSwingDrive".
void FAngularDriveConstraint::SetAngularPositionDrive(bool InEnableSwingDrive, bool InEnableTwistDrive)
{
SwingDrive.bEnablePositionDrive &= InEnableSwingDrive;
TwistDrive.bEnablePositionDrive &= InEnableSwingDrive;
}
void FAngularDriveConstraint::SetAngularVelocityDrive(bool InEnableSwingDrive, bool InEnableTwistDrive)
{
SwingDrive.bEnableVelocityDrive &= InEnableSwingDrive;
TwistDrive.bEnableVelocityDrive &= InEnableSwingDrive;
}
Try using SetAngularVelocityDrive and SetAngularOrientationDrive and check that twist and swing both work as expected.
