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"

In what way are the recommended landscape sizes better exactly?

I'm looking at the recommended landscape sizes from this guide but I really don't understand what do these numbers actually mean

If using more components reduces performance then why do some of the smaller recommended sizes have up to 16 components when they could just have bigger sections?

I suppose it's good to have some components for LOD transitions as the guide says but those recommended sizes supposedly say they are "Sizes that maximize the area while minimizing the number of Landscape components"

Selecting landscape configuration is all about balancing number of components vs size, to get best performance. Higher number of components allows better culling and better layer splatting. More components does not always mean worse performance.
