Help with setting up r15 rig for modelling

[manybloxxer]

I’m trying to make custom accessories for a game so I followed an “old” tutorial on how to set up a rig for modelling but I realized that for some reason it wouldnt work. Here is the tutorial I used Setting up an R15 Block Rig for Modelling (Blender 2.8x+), the attached image is my rig. It was fine until this step:

My rig

I would like to know if this is a non issue for modelling things such as armour

You should be fine and this shouldnt cause any issues, its just the layout of the vertices
