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"

Eye adaptation doesn't work in UE4 above 4.4,

Hi everyone,

I'm wondering why I can't make Eye adaptation working in higher versions of UE4 than 4.4. In 4.4 everything is working without any problem but in 4.6, 4.7 and 4.8 doesn't. AE is switched on in settings, everything is set properly but it looks like it's locked somewhere.

Any help will be greatly appreciated.

Graphic card: NVidia Geforce 970 (DirectX 11)

Kind regards Jon

Product Version: UE 4.8

Hello Jonsnow,

The Eye Adaptation is accessed through the main viewport under show > Post Processing > Eye adaptation.

This enables Eye adaptation.

In order to adjust the settings for Eye Adaptation you will need a post processing volume inside of your scene.

In the details panel of the post processing volume there is a drop down menu for Post Process Settings.

Under that menu go to Auto exposure and you will be able to adjust the Min Brightness and Max Brightness.

Hopefully this will help,

Hello Logan,

thanks for reply but this is not a problem. It looks like this is a problem only on my machine. I'm going to reinstall UE4 and hope it will be ok.

Regards Jon
