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"

Particle system ignoring "Alpha over life" for some reason. Should be simple right?

Your node setup made me realize I had forgotten to connect the alpha channel from my particle in my material output. No wonder my alpha curve was being completely ignored...

The horizontal value of the alpha over life curve needs to be 0-1. So if the lifetime of the particle is 5 seconds, 0 = birth, and 1= death (that occurs after 5 seconds) besides that, you are emitting over 600 of those particles on the same location, so by the time one is faded out, another 599 are fading in or fading out as well. which is why you might not see the result you want.
