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"

Need help to combine face and body's motion data inot UE

Hi everyone. When I read the topic about FaceAR Sample in there: https://docs.unrealengine.com/en-us/Platforms/AR/HandheldAR/FaceARSample.

I am have a model with full skeleton of face and body.

I want to take different types of mocap data and assign them to the same my model within UE4 4.20.

I will transfer mocap data of body by Optitrack system and transfer mocap data of face by iPhone X.

I want to show the body and face can motion in real-time in my model but I am feeling on down the road. I am stuck at there !!! I need your advice for my problems:

  1. Do we need separate face / body (which its skeleton) animation imports (FBX) in UE4 workflow? Or just import a model which has full skeleton and face animation? What is most importand we need to know when do this?

  2. I already transfer successfully the motion of body into UE4. This is topic for do this:https://vimeo.com/282594520 But with the motion of face which use Live Link plugins, I get many misunderstand to do it.

Especial, how to create correct face animation/skeleton? What is the main Blueprint which we can focus for tracking face via iPhone X?

So can you give me more useful information to transfer motion from iPhone X to UE4 .

Thank you so much.

Product Version: UE 4.20
