That is one hell of a task you are trying to do but best way I can suggest to find the asset names is to open the dev kit, go to the map folder you are interested in (if its TheIsland it is Maps/TheIslandSubMaps), find one of the “@#_Near*” where “@” is a letter “#” is a number and “*” is a wildcard (i.e. A1_Near_WIP) that you would be interested in, Right click it > Reference Viewer…, change the depth limit to 2 and maximize the breadth limit, move around to until you find your interested foliage settings, and use the asset name that foliage references (likely with “_C” appended to the end of the name).
