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"

SceneCaptureComponent2D and FOV - calculation rules? Scope for example


I have problem with understanding how to calculate FOV for scope using SceneCaptureComponent2D and render target.

  • I have scope mesh (lens), this is sized like a lens, 1:1.

  • standard game FOV is for now 75

  • I need for example 1,5x magnification

For now, I see ~1.5x magnification I have with FOV on SceneCaptureComponent2D = 2.0 Instead of FOV 50 for example. I can't find documents how it works and how to calculate different FOV for different lenses same size.

This is depending on lens mesh size? Render Target size?

Thank you ++
