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"

Its actually pretty simple. You will need a 2 pass shader, pass 1 is overlay(it draws on top of everything), and transparent, it has the color of the scan. Pass 2 is the normal shader of the object. Now you only need to lerp pass1’s transparency based on something(i used a gameobject’s position) and its done :) I used unity but its generally the same in unreal. youtube video
