In the pic I have an imported landscape created from 3 tiles, I’ve been trying to use procedural foliage on this imported landscape.&nbsp; I haven’t been able to get it to work at all.&nbsp; Any help would be greatly appreciated!

No, collisions have not been set.

Must it have collisions set? How do you place collisions on a tiled landscape!

Foliage relies on collision to know where to place actors. Don’t know much about importing landscapes, but I’m assuming you can set the collision in the external package? ( or if it’s a mesh, in the UE mesh editor ).
