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"

Map Check Error: x elements zero triangles in static mesh y

After using merge actor to merge multiple static meshes into one static mesh, I'm getting this map check error. I chose only "Generate Lightmap UVs" option when merging actors. I specifically get this error when building lightmap.

I looked up the documentation. The entry exists without any explanation. It looks harmless so far, so I can ignore.. but I wonder the cause of this error and how to resolve it properly.
