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"

Can't import animation in 4.20

I can't import any fbx animation into UE 4.20 for any of my characters. The error is always "Mesh containts Root bone as root but animation doesn't contain the root track. Import failed", even though I checked and it is. The other error I get sometimes says that there is no animation data in the fbx. Same fbx files work perfectly in 4.19

EDIT: So I just checked, and it happens only on my converted project from 4.19. New projects on 4.20 work fine. Anybody knows what might be the problem and how to fix it? Thanks

EDIT2: I just looked through the changelog and found this: New: Import Asset Metadata through FBX When you import an FBX file into Unreal, any FbxProperty data that is saved in that file is now imported as well. You can access this metadata in Blueprint or Python scripts that you run in the Unreal Editor. This can help you customize your own asset management pipelines for Unreal based on information about your assets that comes from your content creation tools.

I guess ANY FbxProperty means that namespaces are imported too? :(

Product Version: UE 4.20

Same issue here but it does the same thing with new projects as well.

Are you referencing files and your rig is in a namespace or something like that?

For me the issues seems to be that in 4.20 the importer will add the namespace names infront the mesh and bone names which is why it doesn't find the root bone when importing the animations. Try to import the animation file but dont select and existing skeleton but let it create a new skeleton. See the bone names in the new one.

Yep, I do the same. But rather than copy it I prefer to use the migrate feature.
