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"

UMG element with material does not receive gamma correction on mobile

Engine Version: 4.7.5

Mobile Preview/Device: HDR off, both Android and iOS

See this issue first.

The post above was made regarding gamma correction for UI elements. We noticed it got fixed for images, but still happens for materials on mobile. We are solving it ourselves by adding a gamma correction hack in our UI materials by doing this through feature level switch:

pow(Texture.rgb, 2.2)

We have the impression that all materials on mobile are not being gamma corrected, as some materials become noticeably darker or lighter than the original.
