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"

Some triangles are darker than others.

I'm having some trouble with the shading of some of my meshes in unreal engine. Some triangles appear darker than others, like there is ambient occlusion on random triangles.

[First one is in Unreal Engine with the shading issues (note the lighter triangles on the bottom front of the mesh. Second one is in Substance painter without any shading issues whatsoever.][1] [1]: https://imgur.com/a/oQDCK

Any ideas? This is baked from a high poly mesh without shading issues.

Update: The issue only occurs on skeletal meshes but I can't seem to get rid of it. On a regular mesh the shading works perfectly.

Product Version: UE 4.18

Now I know the issue was with it being a skeletal mesh I could search more specifically for an answer.

"Thanks to user HenrikRyosa from the UnrealEngine forum. The fix was to import with normals and tangents under the Normal import method on the Mesh section of the import window."
