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"

Normal map seams on character

Hi there, we're having a slight problem with the seams on our Normal Maps. First off our mesh is movable and so are the lights. The normal maps are being imported on their default setting as well as the mesh. We're finding in some areas we're getting seams where uv's are split. These seams worsen/improve depending on UV alignment. We were under the impression this was a somewhat legacy problem with Unreal. Please have a look at the attached jpgs for illustration.

Check your mesh tangents, in basic, your individual UV islands should be aligned to a same direction. If you use XSI Softimage you can check the rotation of UV islands by applying tangent and bi-normal property
