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"

There's a couple of things you'll need to set for this, if you get a reference to BP_Sky_Sphere, you'll need to set the boolean value of "Colours Determined by Sun Position" to false, then set the "Cloud Colour" Variable to your desired colour and set the material vector parameter to the new colour.

Something like this.

thank you so much. this solved a lot of my problems. but there's still something I want to know and it has something related to this question. how could I make the color I want to fade into the clouds? EX: white and then fade to black.

Sorry I missed this follow up question.

The principle is pretty much exactly the same, you just need to put a lerp in there to smooth it out.

In this example I am using a timeline to drive an alpha value for the lerp, but you could drive it via any progressing value (e.g. time of day). This is just a linear float going from 0-1 over 10 seconds.
