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 Component Instances in Distance Index Changes

Good afternoon, I'm using UE4 4.22 on Mac OS Mojave. For some reason both ISM and HISM instances that are a certain distance from the player character cannot be removed using their initial indices. This seems really strange to me and I can't figure out why exactly this is the case. To reproduce I have set a thousand mesh instances in a square around my player, each 1000 units away storing each of the corresponding indices in an array. I then iterate through the array and remove each index, but for some reason the indices farthest in the distance are only removed after I get closer to them. Is this expected behavior? Is there any way around this?
