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 access particle positions in the Nvidia Flex UE4 integration?

I am working with the NVIDIA Flex UE4 integration, and am wondering if it is possible to read Flex particle positions in a C++ script at runtime.

From the Flex Artist Tools documentation, I know you can have Soft Bodies attach to and follow rigid shapes, but I am looking to do the opposite of that: I'm trying to attach actors to soft bodies without the use of intervening rigid actors. For example, say I am working with a Flex Soft Body of an octopus. Is there a way to have an audio source actor follow a particular particle on the on the octopus' tentacle as it deforms?

If I could get access to the positions of Flex particles on every frame in a script, then it would be simple to have an actor follow a certain particle, but I can't find any documentation that explains how to do this.

Thanks for answare. Do you know a method for extract coordinate of a flex sphere's mesh?
