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"

Importing a mesh with multiple UV sets

I have several meshes in Maya that have two different UV sets that I have exported under OBJ file. The first set is for the texture, while the second set will be used for UE's lighting. I've unchecked the auto generate lightmap before importing the mesh so the second UV set (the one being used for lighting) will be used. I noticed that UE can only recognize one of those UV sets (the one that is selected in Maya will be exported and used in UE), so how do I get my second UV set to be imported into UE?

Product Version: UE 4.10

In the asset editor can you see your UV channels from the UV channel dropdown on the top bar (It should say UV channel 0)

Hi Spartan, I don't think the OBJ format supports more than 1 UV set. Try exporting using FBX, and make sure your UV channels have different names otherwise it won't work.
