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 tangent space is slightly different between UV shells. Consider making 6 UV islands that you have, a perfect squares, without relaxing them. UVs will have more distortion, but the seams should be less noticable. Additionally, you might need to enable high precision normals in the project settings for more precision with reflections.

try to do it this way: vetex normals on the borders of uv must be splited, and the normal map is re-baked for new vertex normals, at import to recalculate normals MikkTspace.

if you enable the display of vertex normals in the editor, you will see that they are splited at the UVseams, this is a rendering feature, and this should be taken into account by 3d artists.
