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"

Circle To Square in Material

I followed the next video to make a circle with nice particle effects around a capturable platform by my characters : https://www.youtube.com/watch?v=5xUENgiGrRw

In some cases i have square shaped platforms and i would like to create the same effect with a square instead of a circle. How could I do that?

you just need to change the mask used for the opacity to one thats square. you can make one in any basic image editor. or you could attempt to create it though nodes as done in the video but im not sure how to make a square doing that.

This also works, it's much simpler, readable and probably has a better performance. The downside is that you need to use an external program.
