Duplicate Material Group Sorting

[anonymous_user_7d7bd9dc]

Hi, so I’ve been copy pasting nodes from a material to another. Some parameters are members of sorting groups. The issue I’m having is that when copying nodes that belong to a group, the sorting groups get duplicated, even though they already exist in that material. Now I’m trying to change the order of a group but it appears like 10 times and I would have to spot each of its duplicates to enter the right number.

I tried the Cleanup button of the Material Editor with no success. So how do I get rid of all the extra stuff?

I had the same issue in UE4 4.26.2 but if I change ones priority all those groups with the same name have the right priority in the material instance but not in the Material. So I change it for one of the group members in the Material and it works for me.
