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"

Custom material expression not working in 4.20

I have also published a bug report for that one, but here is the problem:

I've followed this tutorial to create blurry outlines: https://www.tomlooman.com/soft-outlines-in-ue4/ And it worked in 4.19. But now in 4.20 it doesnt, there are no compiler errors, but there are these warnings in the output log: alt text

You can download the testproject here: http://www.mediafire.com/file/vcc3g1dnfucuu3z/CustomMaterialError.rar

To reproduce the error, just open up the showcase map and you'll see that the post process material, which uses a custom material funtion, is not compiling.
