It looks like your geometry isn't connected to each other. Is that what you mean? Is the geometry parented to the bones or is it skinned? Its hard to know what the intent of the tutorial was. This might be expected.
Well I guess what I am wondering is how do you make a model bend and twist without it showing those breaks.Okay, so I'm not sure exactly what the issue you're experiencing is. That seems like normal behaviour for the process that you've followed to rig it.
Indeed it does. Thanks man, I appreciate it.You will have to look into a tutorial on skinning. Rigid bind or smooth bind. And you will need a single mesh, likely with more resolution or edge loops. Hope that helps a bit.
