Hello DonBusso,
Here is a screenshot of the input in my project settings.
I tried to use the input “E” in my character blueprint but it does not work either ! Really strange. What’s really weird is that it is working when I use it to pick up my weapon (it I use “E” in the weapon blueprint, I can pick it up (same of the InputAction “Interact”).
Thank you for replying
