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"

Exporting a png sequence for further compositing


I'd like to know whether it's possible to export a png sequence of a screen space GPU particle fire system for further compositing.

Can baking the animation and using a white texture and black background be a way to acquire an alpha matte to make image sequence compositable?

Or is there a way to export a png (RGB + alpha) sequence out of cinematics, matinee or the sequencer?

I need this so bad, please help!

I was hunting around for a way to get alphas to work as well (with exrs mind you).. This would be extremely useful, right now we have little options if we want to enhance our sequence outputs with effects or whatnot outside UE.
