Decal on landscape only?

Hi! I made a decal that I want to apply to certain spots, but only on my landscape. Is it possible to filter out static meshes for decal application?

The only way i know is how to stop a single mesh from recieving decal.
Worst case scenario you might have to do this on every mesh you have xC

Ah, that might works well enough in my case. I would prefer to be able to do it the other way around so that the mesh can still get decals, just not “this” decal.

I also found that shrinking the size of the decal actor so that I could fit it between the assets worked as well, but requires the ground to be completely flat for even placement.
