I have made a custom FComponentVisualizer for one of my components. It works as expected in the level editor, but in the Blueprint Viewport, which is where i actually want to use it, you cannot select any of the things i visualized.

Its very easy to reproduce since this bug also applies to the SplineComponent.  
Repro steps:

- Create a new Actor BP
- Add Spline Component and select it.
- Try to left or right click on the spline point that appears as a white box. (You cant)
- Save blueprint and add to the current level.
- Select the actor and its spline component
- Try to left or right click on the spline point. (Works fine in level Viewport)

Hope this can get fixed, its such a nice feature.

_Edit_  
The workaround is to add the actor to the level, edit it there and apply the changes to the blueprint. (At least for my visualizor)  
_Edit_

Cheers  
Jonas

Hey amimoller-

I’ve entered a ticket for this issue (UE-25178) for further investigation. As you pointed out, the best solution for now would be to edit the instance of the spline once placed in the level.

Cheers
