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"

PrecomputedAOMask node doesn't work

I've tried using this node a few times, both in version 4.19 and 4.20.

I am only testing it now, using it to Lerp between two bright colours, but the Occluded mask never shows up. It seems to simply not work at all.

I'd love to use this node to do more advanced thing sin the future, such as snow and grass masking, but the node itself seems completely inert. Unless there is something else I am meant to do first.

Product Version: UE 4.20

Never Mind. Apparently there is a tick box under world settings called something along the lines of "Use Precomputed Ambient Occlusion mask".

Ticking that fixes the problem, but it seems you have to bake out lighting to see results.
