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 difference between copy and duplicate actor?

I'm a beginner. I cannot find any info on this. So what is the difference between these two options? I'm asking because I cannot understand what is the best way to copy actors around the level and perserve memory and performance i.e. how to make a copy and how to make an instance of an actor so the level loads only the original and it's materials, textures, blueprints etc. Thanks!

Duplicate is just copy+paste.

Instances are:

  • Instanced Static Mesh Component (more performant, but have the same LOD level for all)

  • Hierarchical Instanced Static Mesh Component (can have different LODs but may be buggy)
