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"

I found "SM_GlassTechPanel" from GDC2014 (in marketplace) which is closer to the real glass edge

You can use normal map, normal map is like pixel rotation and each color chanell represent each axis X = Red Y = Green Z = Blue, opposite sites will be black because it gonna be negative numbers and GPU put black color on negative numbers. You can use that map to switch between different series of material nodes (2 materials in one) depending on blue value (Z axis). I'm not experienced with material editor, but you can use "PixelNormalWS" node, problem is it is effected by object rotation, there probably ways to fix it, so treat my answer as starting point ;]
