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"

Two Bone IK vs FABRIK

Hi, with regards to the Animation Blueprints, does anyone know which one is more computationally expensive - two bone IK or FABRIK (for the same number of bones)?

I've got a feeling that my game is running slower with FABRIK on but it would be nice to have a definitive answer please.

Product Version: UE 4.18

Both should be relatively fast algorithms... are you sure IK animation is what's slowing your game down? Have you used the engine profiling tools to confirm that?

Thanks for the quick response!

I'm fairly certain its the graphics that's doing most of the slowing down but I'm trying to optimize the animation as much as possible too.

So there isn't much difference between the two?
