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"

Skeletal animation export from Blender: root motion problem

When I export an animation from Blender and import it into UE4 the first bone in the skeletal hierarchy will be Armature and not my intended root bone. Because of that root motion does'n work.

I'm using the Latest version of Blender and UE4: Blender 2.75 and UE 4.9

The scale and rotation seems to work but the added first bone is a problem. Also this 40 frame long animation is shows as 29 Frames long is the animation view in Persona but the same animation put in a montage has 40 Frames again. For the moment this is not a problem but it may hint at where the problem lies. This is just a prototype but I need root motion.

Skeleton hierarchy Blender

I've tried enabling / disabling "Add Leaf Bones" but it didn't seem to affect anything.
