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"

Dynamic Sun causing shadow Flickering

I am having a weird issue with my project. I set up a simple day/night that updates the directional light and sun direction using a timeline. My shadows work fine without it. But as soon as I add it in. The sun and light moving cause a weird shadow flickering effect. Its every shadow cast that flickers. The trees flicker. The leaves in the trees flicker. The ground flickers.alt text

From what I can gather this is being caused by the Sun's position being too low. I'm exploring code now that shuts off shadows at certain times.
