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"

Office Holiday

Epic Games' offices will be on holiday from June 22nd to July 7th. During this period support will be limited. Our offices will reopen on Monday, July 8th. 

Is there a quick way to check whether a 2nd UV channel exists?

I often import a mesh into UE4 Editor without making the second UV, in order to check if the scale of the mesh is right quickly.Only when it is right, I make the second UV for lighting. Over time,I forgot which mesh I have made the second UV for and which mesh I haven't,so I usually have a trouble —— After building lighting,UE4 Editor notice me the wrong lighting UV.

As we all know,building lighting will spend much time, so I think we need a button to check the lighting UV,and let it ready for all meshes.

Hi LinZhihao -

A quick way to look for what you are asking is to change the view mode in the editor to Lightmap Density. This setting will allow you to not only see what meshes have not been unwrapped but also if your unwraps need to be adjusted across multiple meshes and a color coded chart of the density of each lightmap unwrap in relation to each other.

Thank You

Eric Ketchum
