Where can I find “Merger” button in blender?
Alt+M in Edit Mode. for merger 2 or more vertices (it original “edit mode” features we can’t use it in “object mode”)
I think the problem is when I put it in PME, is always show up in both “object mode” and “edit mode”, that’s why when I click merger in “object mode” from PME blender is crashes(instantly quit) because it’s just have functionality in “Edit Mode”.
I think if I can make it appear only in Edit mode it should be fixed?
