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"

Water Break Effect (Content-Driven Multipass Rendering GDC 2017)

Hi. In the Multipass Rendering GDC Talk they show of an effect which isn't talked about, and that is this water break effect (See Image). Anybody have any idea on how to achieve this?

You will need to have an opaque or masked water material (so that it renders in the depth pass). Then set a high "near blur" value on your post process depth of field to cause the edge of the waterline closest to the camera to blur.

Also, you will probably want to use a pixel depth opacity mask to 'cut off' the edge of the water closest to the camera.
