Sorry for delay - I didn’t receive notification.
I tried again with Wraith character, here are my steps. This is very dirty work, but I use these characters only for tests, so it is ok for me.

  1. Remove material parameter collection;
  2. Open Skeletal Mesh asset - all materials are broken;
  3. Open first material, try to compile - got errors like:
[SM6] Function MF_CharacterEffects: (Node CollectionParameter) CollectionParameter has invalid Collection!
[SM6] Function MF_CharacterEffects: (Node CollectionParameter) CollectionParameter has invalid Collection!
[SM6] Function MF_CharacterEffects: (Node CollectionParameter) CollectionParameter has invalid Collection!
  1. Click on each error - it opens place with unspecified material parameter, I hardcoded it by needed color. In one place Vector4 is used!
  2. That’s it - all materials are fixed (parameters were hardcoded in shared materials functions, so just recompile rest materials).
