-What’s the best way to build the level? It’s a 5x5km surface I think that maybe the best way it’s a landscape?, it’s to much 5x5km?
-If in a future I want to expand it’s possible?
-The landscape has autostreaming level?
-I read something of a modular level design. I think it’s a fast way to build levels is that correct? Where I can learn more of this?
-I have mountains and beach thats suppose some inconvenient?
A few things;
If this is your first project and your introductory text leads me to believe it might be, I would advise against going for a 5^2 kilometers of map, games with terrains that large can have teams up to hundred of people working on it in time spans of years.
Maybe it would be better to recreate a small apart of your town, like its central plaza? You will learn way more more if you create one small environment than repeat the same things you know on a huge map where the likely hood of you giving up before you get to a stage where you’ll learn more thins is huge.
I don’t know if you can expand it but even 5^2 kilometers of map is too much!
I would advice starting with one of Epic’s templates (like the thirdperson template) and simply adding to it. IMO, the best way to build your game (and learn) is to develop a prototype of the functionality for your game first, before you worry about adding more content / art.
The reason I recommend this is because you need to understand UE4’s basic workflow and tools before you can plan your game. Once you have a good idea of the basic tools (like creating basic materials, importing and implementing basic animations, using Blueprint, etc) it will be a LOT easier to start your game prototype.
Start with the Blueprint Thirdperson game template and start adding functionality via Blueprint. Here is a small list of easy things to add:
Add melee animations
Basic HUD with health and stamina
Another NPC with basic AI (a bit more advanced)
Alternatively, you could start with a more robust template like my free Action Platformer Template:
This already has a lot of the basic functionality you will need to start your game, HOWEVER, if you go this route, take the time to look at the code and understand how it works so you can then modify it to your liking :).
thanks for the comment i used all the freebies from Epic apart from the landscape automaterial and size was 15x15 i think :S lol water is easy to do just use a plane then scale it and add the water texture
