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"

How to mask meshes inside a trigger sphere


Is there a way to swap/mask actors that are inside a trigger box or sphere? What I'm trying to achieve is a way to have objects in a level that can only be used inside a trigger box or sphere. Then I would make the trigger size animate from 0 to the size I need to reveal the objects. But also the objects that where in that place would then be hidden. Think of it as sort of a time portal.

I think custom depth could solve a part of this problem, but I can't figure out how to approach the physical part so that the player can only interact with the objects that are visible.
