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"

Getting the Outline (Dark) colors of a Texture?

Hello!

Thank you for coming! Have a seat! I just have a small question! Imagine you have a texture. ıt got white, black, and dark grey. You are lacking a mask material so that is out of option. But, how would you get the black part only then? What kind of "If" would you use, or use at all?

Here is a pic of what I am trying to do;

I need a way to reach this guy's bodies' outlines, which are the darkest parts to light them up. How would you do that?

Thank you for your time!

You'll need to use Clamp then. If black is 0 and white is 1 then you'll need to clamp the texture between 0.2 and 0.5(roughly.)

Mr Jacky, thank you for helping. I used Clamp it kinda works, but.. how to seperate the black colors so I only have an outlining?

Is there any chance that you can demonstrate how to keep only black parts of this simple picture?

You need to use a Lerp, and use your texture as the Alpha of that Lerp.
