We can’t use this one:
Or the nodes in your Event Graph. Instead:
The spline mesh components are spawned dynamically, so we also must bind them in the same manner.
But the On Begin Cursor Over (Spline) still doesnt trigger. Is that because I added a spline mesh to it? (I tought it works like the added spline mesh trigger the spline’s mouse events too)
The spline itself cannot be collided with in any way so this will never work. You will need to rely on the spline mesh components. When you say it IS working, are you sure it’'s working for all spline mesh components?
