After struggling 6 months on building a landscape I give up and ask for your help, I tried World Machine, Terragen and many others tools and nothing gives me a “playable” map. All the enviroments in the marketplace are mostly for scenes but not for real gameplay. Anybody is having same struggle or I’m just overthinking this? I just wanna make a medium open world like a island where you can explore with others, I already done the AIs and purchase some prefabs so all I need is to build all togheter but my main struggle is the landscape. Any help?
