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"

Your unwrap seems not that good for the lightmaps, do you have any overlapping uvs? Is the uv that you have shown only for the post with one part of the fence and this is tiling along the length or ist it the complete fence? You can also let UE create the lightmaps and check out how they solved it.

Hello Virtuee,

I think your Lightmap UVs might be too close together. (Shadows are bleeding over from one face to others)

Try creating (or generating) UVs with more space in between them
