My idea is that I want to make random maps. Lets say I make a landscape (2x2 tile) and put everything i want to be on this tile trees treasure chest etc. I do this with 10 different tile. Can I save them somehow to randomly put them next to each other to make maps slightly random ?
Yep, it’s possible if I understood correctly. But… it will be hard/possibly impossible to get the landscape heights match.
To make the tiles, you can do it inside 3d program or by using ActorMerging inside UE4 - YouTube
Then you need to make a blueprint, something like this Blueprint Generating Procedural Rooms | Live Training | Unreal Engine - YouTube
And then you get the problem of the landscape heights…
But hope this helped, cheers
Look into level instances, also the live training on level streaming dives into what you are talking about a bit (I think i the Q and A section at end.)
