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"

Transition between metallic and non metallic surface?

For realistic results i should use constant 1 for metallic surfaces, and constant 0 for non-metallic surfaces. Problem is that texture mask which defines metallic have some filtering so there are some values between 0-1, that makes some bad results. Theres visible "outline" of metallic material as you can see on the picture. Is there any way to fix this? other than separate chrome parts with geometry. alt text

Look into the node called AntialiasedTextureMask in the material editor.
