Way to linetrace and ignore all but landscape?

What I’m wanting to do is linetrace to place a grass BP, But be able to do it through things so it only would place on the terrain. But I’m having trouble finding anything on how to do something like that. I can’t even really find what object type the landscape is, so its hard to find what only to trace to.

Nevermind, I was able to figure out a way. Had to change project files to add an object type, which I named Terrain. And I set up the line trace to only hit objects of type Terrain,

My work around was to set the line trace to ECC_WorldStatic and then set the mesh collision preset to ignore WorldStatic on all the mesh’s you want to ignore.
