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"

How to make lightning effect like this?

Hello everyone,

I'm trying to make the heavy rain effect. When the lightning goes up, the environment should get a bit brighter. Here is a video to show the effect. The effect appears at 27:28 - 27:35.


I can make lightning visual and rain particles, but how to make the environment a bit brighter when the lightning goes up?

EDIT: An additional image is added. As it can be seen from the image, the environment is really dark in first frame, however, when the lightning goes up, the environment becomes brighter like in the second frame
