You’d need to describe what you’re trying to achieve. In my screenshot you can see how it can be self contained in a single actor.
What’s the big picture here?
Or at least see if you can answer these:
- what’s up with the mesh - placed in the level manually, part of an actor or spawned dynamically?
- where does the mesh get its material assigned / updated
- what’s the relation with the widget & mesh - is it a 1:1 ratio, 1 mesh + 1 widget and that’s it or…?
- does each mesh have its own widget or one widget controls more meshes’ materials
- are you going to have more than level (otherwise you can do some stuff in the LB directly)
