A1: I’m not sure why they would uncheck “deform” for IK bones, unless they didn’t want IK functionality in the rig…I’m all about me some IK though
A2: For rigs you don’t want to apply modifiers except maybe to bake out you final animation for rendering. But you want to apply modifiers [visually] bottom to top. You'll get a warning if you apply in the wrong direction.
Love your video and it solves a number of problems....
But could you do a vid(s) on adding and rigging at least two layers of clothing separate from the original mesh? I did on with a cloth Robe using the pinning method described in the manual and finally got that to work, but I need to add a belt/sword on it and so far no go on rigging the whole thing to one rig....currently using 2.78c
Thanks
