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"

Exponential height fog and changing time of day


Im currently working on an outdoor environment which is mainly lit by a directional light acting as the sun, a skylight and has exponential height fog.

To avoid the main directional light affecting lighting while it moves under the terrain, I have made it fade out to an intensity of 0 before it moves underneath the terrain. The problem im having is that when the intensity of the directional light hits 0, the height fog im using has a sudden change of brightness.

Example here - https://i.gyazo.com/360f18071b9e9b852bd92066ec3ccab8.mp4

Im not sure how to avoid this and get a smooth fade of the fog as the light fades. I have tried keeping the directional light at an extremely low intensity (0.000001) but it still has effects on the fog/lighting while under the terrain.
