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 do I offset a Vector4 node?

I'm making a material function similar to NormalFromHeightmap but accepts Vector4 input (for quick testing). I've ran into the problem of offsetting the UV of the input. Since there's no "UV" pin for a Vector node, I'm stuck. Any help is appreciated!

Product Version: UE 4.19

Wherever you are getting the vector4 input from is probably where you should offset your UVs. If it is reading from a texture you can offset the UVs on it then pass the data into your node.
