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"

パーティクルの色を任意の時間経過で変化させたい

初歩的な質問で申し訳ありません。

パーティクルの色を「青→赤」や「白→黄色」などに変化させたい。 時間経過によっては「青→赤→黄色」などの変化をさせたい。 時間はこちらの任意の時間で設定したいです。

マテリアルの色は、マチネの設定で「新規Vector Material Parameter Trackを追加」で変更できますが、 同じようなことをパーティクルでは設定できますか?

マテリアルのパーティクルファンクションノードである"ParticleColor"と定数ファンクションノードの"Time"を組み合せて使えば自由に変更可能です。

完全に任意のタイミングであれば、Dynamic Material Instanceを使って、ブループリントから指定タイミングを送ってあげてください。以下の記事が参考になると思います。
