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"

How to enable the Flip Green Channel-option?

Hey guys,

I'm using sbsar-files from Substance Designer in Unreal, but I can't flip the green channel, the option is greyed out. I'm wondering if it has something to do with using sbsar-files... alt text

I would be relieved if there's a easy solution to fix this. It would be a bit pointless to manually flip green channels in Photoshop etc when I would want to use substance materials...

Thanks in advance!!

Product Version: UE 4.21

Of course, thank you so much. I didn't even thought about that.
