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 dynamically control DOF focus using Focus Tracking

Hey guys,

I'm using UE4 to render out animated videos and I am using Sequencer and the Cinematic Camera actor. I know the Cinematic Camera actor has some powerful Focus Tracking options. I have a dummy object brought in from blender that serves as the tracking target. But I want to know if its possible to use CircleDOF and change the focus range based on the tracked object.

Product Version: UE 4.13

You need to do it via blueprint. You can add a post process node, and expose the DOF parameters, then you can setup a small logic that calculates the focus points, you can use a line trace for example

Thanks for the reply. But just found out that the Focusing on the Cinematic Camera is already using CircleDOF and just has to drop the Aperture value much lower to get more blur.
