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"

instanced static mesh?

I'm looking for information on what the difference is between a "static mesh actor" and an "instanced static mesh." I've tried googling but can't really find any details on instanced static mesh. I'd like to know when it's best to use each one and why.

When you load a mesh, it's called a "draw call". Each mesh take one drawcall, and if you multiply one mesh by 100, it will cost you 100 unique drawcalls. If you use a instanced static mesh, it will process only one drawcall for the mesh, and the only apply the matrix of transformation.
