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"

Does have Unreal some sort of masks like in Photoshop?

Is any way possible to do this in Unreal Engine? I want to have an unvisible box, which will be hide elements which placed inside. But when one of the elements are moved from this halfway, it's visible, but only outside-of-box piece of element. I saw one tutorial of this thing in Unity, but I can't find it now. Maybe it's just called something different, not mask, and I'm not Googling properly? Something like in picture, but my box must be invisible: alt text alt text

Ok, it's in Blueprint_Communication, example 3.2, u will see the crank highlight, check the GlobalPostProcessVolume search for Blendables, u will see the M_Hightlight material, that use for highlight the crank, by render it on the top level.

You can do the same for your text by adding the PostProcessComponent in the blueprint which contain TextComponent, then add the M_Highlight, then you need to check RenderCustomDepth of TextComponent to true when u want to highlight.
