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"

Its such an open ended question its hard to reply to. The lighting looks all wrong, try staric lighing and baking it? What i can say to help in general is: 1 look into HLOD use for buildings 2 use lod groups, for everything you can. 3 use the foliage tool and not staric meshs if you can as each foliage tyoe is only one 'draw call ' ( look those up if you dont know). 4 AVOID the grass tool,as its the devil itself, till a hoped fix in 4.20. 5 use foliage tool for grass, and if possible turn down shadow use 6 try to keep landscape component total low

Thats it! Hopefull may help others as unreal 4 docs are awful for all the granular detail things that matter

You might want to check out the Graphics Profiling docs. Looking at your shader complexity though, the water seems pretty expensive (Red), and you may want to look at lowering your settings to Low and see how it runs.

The Engine allows you to change so many settings, it is just a case of going through them to gain performance but still have visual fidelity.
