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"

[4.15] DFAO Interior artifacts

I have a scene in 4.15 using realtime lighting / GI and DFAO / ray-traced distance field soft shadows. In these screenshots you can see the Mesh Field visualisation and the DFAO visualisation. This is basically the interior of a small cube room, with windows on either side. As you can see from the DFAO vis. there are square artifacts along the flat surface; yet the mesh field vis. doesn't show and obvious reason why this would be the case. I should also mention that the exterior of this part doesn't show these artifacts.

The mesh is already using quite a high DF scale, and checking 'generate DFAO as if two sided' didn't help. Project scalability is set to epic; and DFAO for the most part works everywhere else, it's just the interior I'm having troubles with. Any tips on improving the quality of DFAO in interiors would be welcome.

No, but I haven't yet tried on a newer version of UE4, so maybe it has changed since 4.15
