Mesh deform issues

I need help with regards to mesh and weight painting. I currently following the RIG Blender's Character Rigging playbook. I am on chapter 3 and trying to apply the weight painting knowledge to my own project file. I am having so weird deforms effecting my mesh once I have parented the mesh to the bones.

I have included a loom video would better explains and shows my issue.

Would you be able to help.

    Hi Joseph,

    It looks like you have 2 layers to the mesh (an outside and an inside)
    Perhaps all the outside verts are weighted correctly to the Spine bone (at least I think it's the spine)
    But those verts on the inside are weighting to a second group that they shouldn't be.

    Try looking at the weights in weight paint mode and/or  click on those verts in edit mode and look in the 'item tab' which will tell you what groups the active vert is weighted to.


    Hope that helps.

    Ok thank you for the explanation. This is a step in the right direction however I came across another little problem. The issue is better explained in this video but is there any way of copying vertices data from one to another?

    Hi Joseph.

    There are a few ways to do what you need.
    The quick way is probably to weight paint (subtract) the weights from that group.

    However you can remove all the verts from a group in the Vertex group tab.
    Select you verts, then highlight the group in that tab, then hit the remove button.



    I can't annotate with this snipping tool but hopefully you see it right next to the "assign" button.


    I have a feeling that you haven't taken the fundamentals course before tackling this one though.
    Am I right!?

    I even waited for you to finish, right at the start of the course. haha

    Hi Wayne, 


    Thank you for you response. 

    I will try all the ways you mentioned. 

    hahaha yes you got me. I will go back to that course to cover any missing gaps in my knowledge.
