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"

Accessing a switch parameter from a material instance dynamic in blueprint

I can access and modify a scalar parameter just fine with a material instance dynamic. Is there a reason I can't modify a switch parameter in the same way?

Thanks in advance!

There is. Switches are MEANT to be static and unchangeable. The value you give a switch in your MID gets compiled into the shader code and the inactive branch is left out completely.

Thanks, that makes sense. So if I wanted to make, say, a dynamic switch, for the time being I should just run it as a scalar.
