I’m trying to achieve a simple objective - to remove one non-breakable rock and foliage around from default map. I installed the Dev Kit and I can run it with no problem. I created a new folder in Mods and copied a content of TheIslandSubMaps to it. I loaded TheIsland.umap from my mod directory. I loaded B1_Far_WIP.umap and B1_Near_WIP.umap from Levels dialog, I found required rock and foliage and I deleted it. Then I saved the levels.
Now I have a problem to get it working in singleplayer game. I tried to cook it as a custom map (TheIsland.umap), I loaded it to Steam Workshop and I subsribed it. But size of the mod is still in few kbytes only. When I start the game, I see it in a list of mod/custom map but when I start the game, the rock is still there. Any advice how to make it working? I went through topics here in forum but I did not find an answer. It must be something easy but I cannot get it. You help is appreciated.
