Hello,

Since UE-31722 fix adding categories to Material functions become impossible. It simply does nothing and shows material function as uncategorized.

Steps to reproduce:

  1. Create material function
  2. Expose to Library in Details
  3. Add new category in Details - Library categories text
  4. Type in any text as title
  5. Compile the function
  6. Try to call this function in any material

Edit: You can find dozens of UE4 native material functions in Uncategorized which have proper categories, yet all shown only in Uncategorized.

Thank you,
Dmitry.

I select function and type new category name inside Category field. It works fine for me.

I can find this category in list and function under it.
