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"

Gradient between two colors

I have the attached material with two different colours, where the position between them is set during game play.

I want to soften the line between them / apply a gradient.

I have tried several gradient nodes, and swapping the "absolute world position" for a "texture coordinate" but have not managed it.

Can anyone point me in the rights direction?

Do you really need this "Max(,0)" node there?
