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"


以前4.18での動画音声の出力方法を聞いた際に下記のURLを教えていただきました。 https://docs.unrealengine.com/latest/INT/Engine/MediaFramework/QuickStart/index.html

この通りにブループリントを使用することで音声の再生は可能になったのですが、 音量の変更方法がわかりません。

4.18以前は[Set Volume Multiplier]で変更していたので、 ブループリントの親クラスを[AmbientSound]にしてもみたのですが、 数値を変えても音量の変化がありませんでした。


Product Version: UE 4.18

確かに4.18のMedia Soundコンポーネントには、音量調整のパラメータが見当たりませんね。

正しい解決策とは思えませんが、Sound ClassのVolumeパラメータを使用して音量を変更してみてはいかがでしょう?
