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"

Ambient Occlusion with dynamic mesh interaction not working

Good morning,

I am working on a project where there's a lot of sequences and animations. I've been using SSAO and DFAO to add ambient occlusion in my scenes. It's working quite nicely for the environment. The problematic is that where there should be contact with dynamic objects and the landscape, or if 2 characters are interacting with one another, there's no ambient occlusion. It looks a bit better when I enable DFAO, but it still lacking the AO from contact with ground or dymanic object. And when I'm rendering my sequence, there's a lot of ghosting in frames.

I can't show any screenshots, so I'll use one from the sequencer example of UE4. alt text I would really appreciate your help, I've been trying to fix this for many days.

Thank you for your time and your help

Product Version: UE 4.13
