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 use shaders in the editor?

If I declare a global shader in my code using the tutorials available, it works, compiles, and UE4 opens perfectly...seems like it should be somewhere, but WHERE?... I've only seen one example where I should create a c++ function that sends data to the gpu, etc.

How do artists use global shaders in the editor? is it in the material editor? Where are the shaders? . I've seen people using Custom nodes to add HLSL code, but what if I've declared a usf file and loaded it using a class and Macros? Is it necessary to write a function to send the data and use the shader in the gpu?.

Where is my shader located? Can I see the list of shaders declared and loaded?

Thanks
