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: IK feet + root motion if you got to keep all bones parented to Root?

Hello unreal dwellers!

I'm attempting to create walk cycle in Blender and naturally i've used IK for feet to stick them to the ground. Now i can't export animation since i'm getting multiple root bones error (bone hierarchy screenshot below).

In the other topic I saw an advice to parent all of the bones to Root bone (Torso is supposed to be used for root motion in that case) or to rename Skeleton to Root. In first case - my ik bones will follow "Torso" then which will screw animation and will make feet IK pretty much pointless; In the "rename Skeleton" case root motion will be missing since Skeleton itself as an object is not animated.

So how do you properly export such animation? Hopefully without baking it.

I've asked this question here https://forums.unrealengine.com/development-discussion/animation/1420874-leg-ik-based-animation-root-motion as well a week ago, but it seems that forum community is not really active.
