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"

Hey Maxxi -

You can open up the Skybox in the Static Mesh Editor and under Build Settings click on Auto Generate UVs and this will replace UV Unwrap 1 with an unwrap that does not overlap, make sure that the LightMap Channel is set to 1 in the Static Mesh Settings and you should not have this error again. I have also entered this in as a bug (UE-4534).

Thank You

Eric Ketchum

Thanks for your answer Eric, I auto regenerated uvs on channel 1 but still the same pb when I build the lighting! Olivier

Did you go under the Static Mesh settings and assign the new UV Channel 1 into the Light Map Resolution Channel?

I have this problem with a different mesh, and changing the lightmap coordinate index hasn't affected the problem either.
