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"

making linear gradient node fade out obvious

Hi guys I have this linear gradient node I"m using to fade out an shockwave effect. I want it to start out in the middle at full color and as expands towards the outside edges it fades-like a fading ripple.

Right now the linear gradient is just too strong? I tried messing with a "smoothcurve" node and it's kind of in the right idea of what I want but not really since it was broken. By which I mean it was fading from the bottom right center in this fibonacci like pattern (looked like one of those old school radar screens).

Any advice on how to ramp up the linear gradient so the fade out is more obvious?

thanks

[edit]

I was able to adjust the ripple so it starts faded from the inside and gets colored as it goes out, but I need the opposite. I tried to oneminus, but it just went back to how it was before (linear gradient not being very noticeable).
