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"

Get bone influences in Skinned Mesh

How can I figure out which bones influence a given vertex in a UPoseableMeshComponent? I can retrieve information on the various bones, and I can compute the position of all vertices according to the current bone transforms, but I would like to figure out what all the bone influences are, at runtime.

Essentially what I want to do is, for a given bone (e.g. a bone for the left upper arm), I want to figure out which vertices to associate to that bone based on the bone influences, so that I can construct a simplified convex hull around these vertices (I'm using a custom physics engine) and this convex hull would represent the left upper arm for my character. How can I go about retrieving these bone influences?
