Create a Child Blueprint Class of the BP_MasterResource
Open DT_Resources Data Table and add a New Row, set “ResourceToSpawn” to your new Child Blueprint Class that you just created.
Inside DT_Resources, make sure you set ResourceMesh to EXACTLY the same as your foliage mesh.
Open up your Child Blueprint Class, change it’s FoliageSettings to “MyNewTree”.
