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"

How to set a parameter to all instances of a material?

I have a mastermaterial that calculates a colour for a certain effect based on some variables that then gets used in various ways depending on the material instance’s settings - which is stupid. Instead, I would like to calculate that colour once per frame and then feed it to all of the material instances to save some performance. Is it possible to do something with blueprints that would ”Set parameter for all instances of this master material to X”?

Hi, you can use Material Parameter Collections for this.

How did I not know about this? I’ve added so much bloat to replicate something like this... Thank you so much!
