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"

UV Overlapping

Hello,

I've been working for a few hours on a building model, composed of A LOT of different meshes (I just hate making a big one, cause I just can't put my UV correctly on one big model). I imported it in blender, looks good, but when I do some lighting build, it says my Ovject's UV are overlapping by 1.3%. I checked, it did create the lightmap, and it did apply it correctly. Only 1.3% ? I do'nt understand.

Hope you can help, Cheers

All the information you need about this can be found here: https://forums.unrealengine.com/showthread.php?748-Error-Lightmap-UV-are-overlapping-by-40

Additionally, if your uv's are overlapping themselves or are inverted, even the auto generator cant fix it.

Okay, so.. Seems like the error is fixed after a few tries with settings. However, it does that kind of odd lighting: alt text

It looks like either your UVs are still overlapping, or your lightmap resolution for that object is vastly too small. Try increasing the resolution and see if that helps.
