According to file catalogs C:\Users…\mods\local\mod_name\resources_common\terrain\colorcorrection_json, the json file seems doesn’t work in the game, the 2019 Winter Celebration Mod json file doesn’t work also.
Up to now, I can only make the json file work by rewriting local files under the Steam folder so that I cannot uplode this colorcorrection_json file as a mod.
Now I’m trapped. Is this a bug in the game or just the workshop doesn’t support this json files in mod?
