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"

Randomize Material

Hi guys, I have a scene (screenshots below) and I want to randomize the lights on the tall buildings, The scene is entirely one mesh with multiple materials applied... For the tall buildings the UV map is tiled vertically and slightly horizontally...

My question is can I use a masking method to hide random portions of each material, without it tiling like the rest of the other material being used.... Heres what I have...

The material currently setup alt text

And the scene in question alt text

Unsure if I've explained myself correctly lol, but hopefully you get the jist of it...
