How to get mesh information for point cloud collision detection?

I work with the lidar point cloud plugin. My goal is to detect when an actor collides with a point in the point cloud and even color the hit points.

There are blueprints for the plugin that allow me to choose between detecting points inside a sphere, a box and point which have been hit by a ray. My problem is that it is possible to make for simple shapes like boxes and spheres but otherwise i can not so easily create the detection out of these shapes for a more complex actor. In addition I can only get the middlepoint of the actor via the get actor location node and have to calibrate the distances and direction for the shapes.

I know it should be possible when i am able to get the point cloud to detect collisions but even after i enabled the feature for the cloud and the actors, they would just pass through.

Does anyone have had the same problem and could help me with that?

Btw I am new to ue5 so excuse me when there’s a simple solution which I am not seeing.

Make sure to build collision for your point cloud before you try to line trace
