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"

Color picker different to color in engine.

I have been annoyed about this bug since the release of UE4 however I never reported it because I kept hoping that it may be fixed in the next update.

The color that is displayed in the color picker, whether via sliders or Hex ID, is different from the actual color that is shown in engine... Even in the color variables' display?!

Hey WarLord -

The difference you are seeing between the Color Picker and the Final Engine Color is based on the Color Space you are using in the Color Picker. Without sRGB checked you are using a Linear RGB colorspace which allows you to see the mathematically linear color (16 bit) inputted into the rendering engine, sRGB is the final converted color (8 bit) that will be shown on the monitor based on current Color standards and current HDTV and CPU Monitor standards. It is also the default colorspace for most HDTV and Montiors which do not use a Wide Gamut, so it is what the Editor uses to preview items outside of the color picker to ensure a consistent appearance across multiple platforms.

There is a wonderful explanation of the math behind this conversion over at Stackoverflow, http://stackoverflow.com/questions/12524623/what-are-the-practical-differences-when-working-with-colors-in-a-linear-vs-a-no/12894053#12894053

Thank You
