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"

Blender normals looks worng after inport to ue4

alt text

I duplicated and rotated this box at first. The original one is fine.

But import in ue4 looks bad.

alt text

I recalculated normals but it does nothing. So I try flipping the normals.

But it looks right. That confused me.

When you are importing the fbx from blender, are you allowing UE4 to compute the normals, and using the Mikk TSpace method? That is how I import the fbx, and have not ran into a problem with normals, as well as this way fixes a few other issues.

Hope this helps,

It not worked,but I find if you scale it to rotate something in Blender may cause the problem.
