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"

Localized Fog or Accessing Post Process Volume Blend Radius Alpha

So what I'm trying to do is use the Exponential Height Fog in certain locations of my open world game. I'm also using Post Process Volumes in these areas, and was hoping there was some way to access the weight or alpha value of the Post Process Volume's Blend Radius (the one that sees how far away from the surface of the volume the player is) so that I could smoothly blend the density of my fog based on how close you are to the region, rather than just having it fade in or out once you enter the region.

Maybe there's an easier way to do this (I can certainly think of complicated ways to do the same thing), but if I could access that value, it'd be by far the easiest method.
