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"

Validate lightmapping UVs before building?

Hello everyone, Is there anyway to check whether the 2nd UV channel of an asset is ready or not for lighting building? In complex scenes I often find myself in the frustrating situation of building the lighting only to receive an error message after 15-30min of processing. Isn't there in the asset editor a button such as "check lightmass UVs"? As a workaround, for now I have been loading the mesh in an empty project, on which I build a preview lighting just to check the UVs. Thanks a lot! Regards, LUCAS

Hi Lucascorato,

Unfortunately, there isn't a check to see if there are overlapping UVs without opening and and seeing if you're got issues with your UVs for your assets before hand.

I think this would be a great idea though! I've submitted a feature request for this. (TTP: 348872)

Thank you!

What's the state of this? Is there anyway to make this check beforehand now?
