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"

Hi L34D3R,

This looks like it's likely due to lower lightmap resolution for your wall(s).

  • Is that wall you're indicating a single piece of geometry or are all the walls a single piece of geometry?

  • Can you post a screenshot of your UV layout for this wall?

  • What is the lightmap resolution that you've set? If it's at the default 64 try using a higher value.

  • Can you also post a screenshot of your Lightmap Density view focused on this wall. You can access this view in the Viewport > View Mode drop-down > Lightmap Density.

Thank you!

Tim

But would the lines caused by low margin UVs be flickering?
