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"

Overlapping UVs?

Hey guys, currently I am working on my first asset for UE4.

My Problem is: I am building a trashbin with four wheels that will be all textured the same way. Would you suggest to layer the UVs of the wheels upon each other for saving texture size or would you put them all seperatley on the UV layout? I know, that overlapping UVs will cause trouble with light maps in UE4.

I think this is pretty basic stuff and there should be a way how a situation like that is handled properlyand professional. Does anyone know the best way to solve this?

Cheers and thanks, Till

Product Version: UE 4.12

You can use two sets of UVs. One for the textures and another for your lightmaps. That way you can have better resolution on your main textures and then also have a UV set for your lightmap that does not have any overlaps and has appropriate padding.
