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"

Possible bug in "Use Inverse Square Falloff", blue screen flicker

I was looking for a per pixel translucent lighting solution and found out about the surface forwardshading method, when i enabled that the method to my glass material and ran some test, when i rotated the camera to the front of my vehicle with all the lighting on it made the entire screen flicker black/blue. https://gyazo.com/d5ef844cb59e9aa42537ba546188174e

I thought that was the issue as i noticed the flicker after switching translucent material methods, after further investigation I found it is the Use Inverse Square falloff setting in the spotlight, combine that with 2 spotlights in close proximity aiming at a camera will cause the blue/black flicker of the entire screen.

The headlights consist out of 2 spotlights combined with an emissive texture, it only flickers blue/black when looking into a headlight when both spotlights are on (lowbeam and highbeam)

Kind regards,

Product Version: UE 4.21
