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"

Visual Artifacts when using emissive with reflections and anti aliasing

I'm having some issues with the rendering which is causing me to lose my mind.

Have a look at this short clip


two issues here:

  • occasionally, you will see those massive white flashes in the reflections

  • as soon as you stop moving and turning, the white lines in the distance will fade off to a black (some of them!) which makes me think this is related to AA

I have tried,

  • playing with all the settings including r.ssr quality, temporal AA / FXAA (fxaa is way worse)

  • post-processing and rendering quality settings

  • material options including Responsive AA

See screenshot as well

Any help much appreciated, I've scoured the web, tried many things and couldn't find a proper answer.

Hey keyle -

I think I am going to need a little more information to help diagnosis your problem. The very thin white bands that appear on your pillars in the foreground of your picture (assuming you did no major changes to the material) are probably the bands generated in your material as it will generate squares. But beyond that observation, I need to know how you have set up the Reflections in your level and the lighting arrangement. Specifically are you using Stationary, Static or Movable Lighting and what type as well as are your using Screen Space Reflections only or are you also using a Sphere Capture Actor?

Thank You

Eric Ketchum
