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"

Why does my static mesh have weird mark pattern after lighting build?


I am using 4.4 update preview. I just imported a .fbx as static mesh, droped it in the scene and it looks ok before lighting build, but after I build, the mesh has some weird marks on it.

Anyone knows how to get rid of them ? Thank you.

It looks like you may need to setup a second channel UV for your lightmap. You can do this in your 3d modeling software that you are using.

If you have already setup a second channel for your lightmap make sure to increase the lightmap resolution in the mesh viewer/editor or the details panel. The default resolution is 32. Try something like 64, 128, 256 to see if that helps.

Thank you!
