I know that there is Bind Layer, Bind Points, and Flexi Binding (ctrl+shift+f) and that in most rigs all three of these are used together
Yes I believe that's true. You can use one or any combination of them together in most cases.
Now the next logical question I had when learning this was, "How do I know which one is better for MY rig".
Well, Good luck with that one. This is something very hard to answer simply. I Believe it just comes down to experience.
Just create another one of them proof of concept files I spook of and give it a go.
Speaking of proof of concept. Your South part one is good. I see a bunch of lessons learned in that one. Good Job grass hopper. (as I give you a bowl). I think your doing fine already. all that rigging stuff your worried about will be a thing of the past soon.
The process is basically the same whether you have one layer or several. In fact if you look at the rig I made with your art. I have the pocket on its own layer. So yes, you just assign or Bind each layer or points or whatever the same bone.True, but I think the thing what I'm trying to figure out is... say I put the overalls with out the details on one layer and then had the details of the overall - like the big pocket - on another layer. Is it just by combining the two layers with one bone how you make it work? and then just do the fine detailing with smart bones.
I hope my answer isn't to overly simplified, because again there are a couple of way to do it. It just depends on the rig.
Yes, either smart bones OR maybe even flexi binding.So if you didn't use patches on something like say...the arm to the body. Would you just correct all the with smart bones? I also haven't heard too many good things about patch layers...
I did see a tutorial video for Anime Studio 10 that adds a new feature that looks like its going to make this a little easier.
But, its not difficult to do with AS 9.5 either.
Good luck to ya
