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"

Getting joint local transform

I am trying to get the local transform value of the joint in my skeletal mesh so that I can use it to drive a variable.

The only option I can find though is transform from bone space, which only gives me its current world location.

Is there a way to get it's local transformation?

One thing I thought about was simply deducting the joints value from the parents value, but that doesn't take into account that the y axis might be at an angle. Is there an easy way to get this information or will I need to calculate it in my BP?

Thanks in advance,

You can use Get Direction Between Socket node. As long as you consider your root joint as origin point (0, 0, 0), you can get other joints' transform relative to your root joint.

Below is an example of getting the local transform of the pelvis joint relative to the root joint. alt text
