an acc made of an object floats and looks awful in cas

Hi. It must be assigned to the head bone. Also, delete uv_1 and vertex paint the mesh with black to disable morphing

- create a new vertex group with +, double-click to rename, paste b__Head__
- in edit mode select the whole mesh with A, assign it to the head bone

- delete uv_1 with - button;
- switch to vertex paint mode, click on the color, choose black, press Shift K to flood the mesh with it;

You can change shading to solid to see it
It’s the icon next to Vertex paint mode

-change shading to solid;
- change the color;
- Paint - Set vertex color

b__CAS_LowerMouthArea__ is a slider that makes lips bigger, so if you want it to follow animation, you need to sample weights from the nearby area on the head itself

Well, you have two options. One is to transfer weights from a specific vertex and remove unused ones with a plugin. Another is to add them manually as you've already done

- expand the rig, make the head_2 selectable;
- select it, switch to edit mode (TAB);
- disable Limit selection to visible, select a vertex closest to it, you'll see what bones affect it;
- select the first bone in the list, in the vertex group list double-click to rename it, copy the name, enter its value;
- select the stick, in edit mode select all of it with A, rename the head bone to b__L_Mouth__, click Assign;
- repeat with other bones, while changing values. I guess you could try assigning it to b__CAS_LowerMouthArea__ as well. Does not make sense for the stick to become bigger with lips, but otherwise it will clip into them, so...;



- if you do not want that, you could try renaming b__CAS_LowerMouthArea__ to b__Head__ and see how the mesh will behave;
- if still not good, delete the head bone and normalize all with unchecked Lock active


Normally, the adaptation process is very easy and does not require jumping over hoops. So if the goal is to learn how to do something rather than create a specific item, you should pick something that exists among maxis ones. Then you simply transfer all the data and thats it. These maneuvers wont really teach you much

If a stick is assigned to the head bone, it will move with the head bone only. If the head's bone value is 0.5, it will affect the stick in half its strength. This is the idea behind how weights work.
You want the whole stick to move exactly like that one selected vertex. That vertex is affected by b__L_Mouth__ by 0.173, so it follows this bone to this extent. b__LoLip__ affects it by 0.463, so almost in half its strength, etc.

- select the stick, rename b__Head__ to b__L_Mouth__, change value to 0.173, click assign;
- create a new bone, name it b__CAS_LowerMouthArea__, value to 0.114, assign ( or replace it with b__Head__ );
- create b__LoLip__, value to 0.251, assign;
- create b__L_LoLip__, value to 0.463, assign
- the sum of these weights is not actually 1, but thats ok, s4s will normalize them

You need to enter a new value manually before assigning it
