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"

Niagara not rendering distortion

I'm having issues trying to figure out how to render a material sprite with refraction and no color.

The material looks fine in the material Editor:

But this doesn't render in Niagara. I can have any other material here and it renders fine. alt text

Anyone know what is going on here and how to fix it? I have checked use with Niagara sprites in the Usage section alt text

Update, i put this material on a mesh plane and there is still no effect. However if it put it on mesh sphere and it takes effect. Is this a bug?
