How do you find the floor in blueprints using a LineTrace?

I’m trying to use LineTraces to find the floor and either I’m getting spurious objects like trigger volumes (which are in my world) or I’m missing the floor entirely. The line traces are based on level-designer-defined points above the floor. (which may not be at a consistent height).

If my character can stand on it, then I want a result from my LineTrace… if it’s a trigger volume, I don’t want it in the list.

How do I define a LineTrace to satisfy those requirements?

Use “LineTrace for Objects” node and plug in a Make Array that contains only the collision Object Types you want it to notice.

the Line Trace by Channel node seems like it would work too but I’m new to this.
