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"

Motion Vectors

Hey All,

Is there a common agreed best way to get an overall motion vector pass out of an unreal render, preferably one that is formatted forward backward (uv = r/g and g/b), so it can be mixed with or used as motion vectors coming from traditional 3D packages such as Maya/Max and/or altered to be used properly in Nuke/Fusion

Have been trying to think of maybe using a custom scene material overwrite to put in GBuffer, but no luck so far in finding anything that explains where motion vectors are stored.

Thanks much for the help !
