Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

What is the best way to approach developing an open-world game?

Hey friends. I am working on an open-world game and was wondering what the best way would be to approach this and where to start. If anyone could give their input on this it would be greatly appreciated. Thanks! I am relatively new to UE and if anyone has any advice feel free to let me know.

Product Version: UE 4.19

Firstly, for open world game World Composition system is necessary https://docs.unrealengine.com/en-us/Engine/LevelStreaming/WorldBrowser This looks worse that works, is not hard to create this system in game. World Composition is important because two main reasons:

1 game optimization

2 editor optimization - with plenty level, even on very good machine it can make work really slow and laggy. World Composition system solves it, you can work on single landscape part (or city, space - whatever)

If you game area will be landscape based, most important is good terrain, landscape. I prefer generated terrain or real from terrain.party, but it always must be tweaked later in other software. Simple rule - beauty terrain, mountains mostly are non walkable and looks bad from close distance.

For creating landscape, editor is good for some tweaks, depending on game design, maybe you can use it, but you need other software like a World Machine or much cheaper L3DT - however, not that amazing too.

Creating landscape take care on Epic dimensions https://docs.unrealengine.com/en-us/Engine/Landscape/TechnicalGuide#recommendedlandscapesizes

Most important, this is hard work and if this is your first game, maybe try something simpler. And don't do basic error like a others - create environment then game code. Code should be first or work on both - this is connected.
