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"

Why do my dynamic lights cast rippled effects?

I include a picture of a corridor that has a dynamic pointlight. Depending on the camera angle the light casts these dynamic ripple effects on walls. the effects are not there if the light is set to static.

Any idea what might cause this would be appreciated alt text

This is caused by dynamic lights with sharp angles on an actor and large radius for Spot/Point lights.

This can be tweaked by adjusting the settings for Point/Spot lights for Shadow Bias and Shadow Filter Sharpen to get better results.
