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"

Shimmer on edges / lines

I'm getting this odd artifact on a lot of objects and lines. Sometimes objects bounce around a few pixels constantly.

This happens in the editor, play mode and after it is launched. Is there any way to fix this, and is there a term for what is happening?

Hi Devinean,

What you are seeing is shimmering caused by Anti-Aliasing. It is usually caused by reflections and lighting. You can adjust this by adding a Post Process volume to the level and changing the AA Method.

https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/AntiAliasing/index.html

If this doesn't help, feel free to post your dxdiag and we can take a look at your specs.

Thanks, TJ

Aha! Had to uncheck Temporal AA. Thanks!

I have one other small problem, reflections have some form of artifacting as well as the shimmer on the 3d text on the walls.

DxDiag

Is it something that can be changed or should I just learn to deal with it?

Thanks Again!

What you are seeing is the slight bumpy variations in the normal map channel of that floor material. Here is a very smooth reflective material in comparison.

I see, it's one of those things that once you see it, it drive you crazy.

But now I know that it's normal, it won't bother me! Thanks!
