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 do I fix light flickering artifacts on my characters

How do I fix light flickering artifacts on my characters? my characters get some strange flashing flickering light on their surface, looks a lot like Z-Fighting.

It happens when the directional light is set to stationary, when I set it do dynamic or static the artifacts disappear.

Here's a video of the issue. https://youtu.be/40r5MlACovk

Just to update, we are unable to reproduce this issue on the latest version of Mac OS Sierra (10.12.2). Try updating you OS if you can.

Fixed by toggling Dithered LODTransition on (off by default) on the character material, can someone elaborate on what this does and if it really is the proper way to fix this issue? Don't want a side effect of this "fix" to bite me later down the line. Still pretty new to Unreal Engine.
