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"

Media player from a Webcam URL stops working on runtime

Hi all, As you can see in the picture below, I have a Webcam live feeding into a media player --> media texture --> material assigned on a Plane in a level which is working fine. alt text

Now as soon as I hit Play, the media texture goes black on runtime.
I think the reason is: In the editor, as in the picture below, it actually won't show a Webcam captured video until I manually choose a correct stream option.

So I guess I have to do the same thing in the blueprint. After "Open Url" node, is there any blueprint node that I can use to select a stream playback option? Please help~~ Thank you for reading :-)

Solved. My bad, it was easy and simple. All I needed was "Select Track" node to specify a track index number.
