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 doesnt work?

Hi i'm having this wierd behavior of the color picker:

I'm triying to get the colour of a texture using unlit mode just to match the properties in a new material, 2 wierd things happend: 1- The colour doesnt match 2- the color picker windows just closes every time I try to get a color with the picker, and it doesn,t save the color I just picked!

So it seems the color picker windows is just a litle trick to make you loose your time!

Hi dogrush -

The Color Picker closing on you have been fixed in 4.8 and you should be able to pick any color you desire drawn on the screen. As far as the color behavior in the Color Picker to Material, it is hard to tell from your example what you arr are directly referencing. Also remember that the Material Viewport has a lighting in it applied and also the physically based components of Roughness and Metallic which can affect color when combined with a lighting environment. You are doing a comparison with an unlit scene which will never truly match the material color.

Thank You

Eric Ketchum

Hi -

So I understand you frustration now. The issue revolves around trying to pull the color information from the viewscreen itself. Even in unlit mode, there are several different color conversions that are taking place to render out the scene with all post processing and effects.(Unlit mode only removes lighting.)

The most accurate way to pull color information is directly from the bitmap itself which can be done directly from the Content Browser or from the Texture Editor.

I've included a sample project for demonstration:

Perfect! now I get it, so I have to open the texture and color pick the texture instead of color picking the scene... also by doing this the color picker doesn't close (I'm still in 4.7)

Thnx!!!
