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"

Engine Color Space?

Hi guys, could someone to explain me which color space does UE4 use by default? and where or how can I change it?

For example in unity you can easily choose from Gamma or Linear space in lighting options, and that has an impact on how lighting affects textures and are presented on your monitor.

UE4 renders in linear space. There is no simple option to change to gamma space, but there is also no real need to do so. Unity supports it, as rendering in gamma space is slightly cheaper on legacy devices, but any device that can run UE4 should be able to do so in linear space.

Hi,

UE4 does indeed render everything in linear, however there is a lot more that goes into what a colorspace is. A colorspace refers to two things, the color gamut (aka the total range of colors that can be displayed in the render) and the encoding/white point.

linear and gamma correction have to do with "brightness mapping" and displaying things in a manner that more closely matches the perception of human eyes.

A colorspace is a map telling your rendering engine how much blue is "maximum blue" or how much red is "maximum red" The human eye can see more colors than a monitor can display! As we move into HDR displays this will become more relevant!
