Get results of Spring Arm collision test

Is there a way to get the results of the camera / spring arm collision test? I have the third person template and need a bool value that’s true if camera is colliding with something, respectively false when camera freely follow the player. What would be the best approach to this?

Thanks,
Florian

Sorry to shamelessly bump this. Does someone have an idea on how to get the result of the spring arm camera collision test in blueprint?
