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"

This looks like a custom mesh so I am assuming you built it in a 3d modeling program and imported it. If so, the split it into two FBX files. One for the base and one for the boom. When exporting the boom to fbx, move the mesh so that the origin is your rotate point. The in UE4 create a new Actor blueprint and use Set Relative Rotation node on the boom. Here are screenshots of how I just did it for a catapult I am playing around with. The UpdateRotation custom event in screenshot 2 is connected to the Set Timer by Event in screenshot 1.
