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"

Smoothing groups are missing when importing FBX file into UE 4.19.x / 4.20.x

Has anyone experienced the following issue - FBX file with skeletal mesh with smoothing groups imports into UE4 without smoothing groups (yet, in Autodesk FBX Converter smoothing groups are clearly present) ?

I don't recall having this issue before, but I didn't work with skeletal meshes to much in the past.

Thanks beforehand

Product Version: UE 4.20

I have the same issue in 4.21. Importing an .fbx file, I get an error message saying no smoothing group present. The imported asset looks low poly in UE4 although the mesh is detailed. When i import the same .fbx file in Autodesk fbx viewer, asset looks good and smooth.

in UE4: alt text

in Autodesk online viewer: alt text
