View Full Version : more character rigging help please!!!
Clive-H-Jones 01-01-2006, 10:13 PM hi again
aargh. ok, so i got that other problem sorted out ok. just tidying some bits up today - missed weight map points etc - all sorted BUT NOW my 'shoulder' bones just WILL NOT seem to parent to my 'root' bone!
(attached pics may help explain)
i did sort it out this afternoon somehow but then my pc crashed before i saved! i tried doing the same thing again (at least i thought it was the same thing!) and now the arms go all twisted up and weird. i'm sure before all i did was go into schematic view and ctrl click each shoulder to the root thus making them children and all ok!
please please please...any help on this mucho appreciated as its driving me nuts!

Can you post the object/scene file?

Yeah scene and object file would be handy. Is Parent in Place on?

Go to frame 0 where your bones are in their default positions. Turn off IK. Select all bones then hit the "r" key.

BTW: use the classic scene editor to select all bone of current object..

Pooby was right from the start. I think you've been sloopy!
:)
Imho you have your pitches and your headings all messed up. One bone is alinged on the pitch and the next on the heading and so on. Ideally they should all be aligned on the same rotational axis (they definatly don't have to be though). The point however is, that you should take more care how the bones are aligned. Open up two sessions of Layout and compare how the bones are aligned in the original an the attached version below. I can't say that it should be like this, I'm not a pro, but I find rigs easier to work with if things are aligned more carefully. Imho you started out wrong. Pivot Rotation on the "root" bone is <180, -3, 89.9>. It could just aswell have been <0,180,0>! You shouldn't rotate the bank of any bone unless you explicitly want to change the alignment. To fix things I just removed recorded pivot rotations, moved, rotated and align pitch-ed bones until it matched the original. Last, I rested all bones.
Other than that you just have a couple of body parts parented to the wrong place. You can fix that using the suggestions given above. You'll also have to reparent the goals to something else. Choose is yours. I guess the most common options is to the object itself.
You'll have to excuse me if I've missunderstood the intentions of the rig. Perhaps you aligned the bones the way you did for reasons not clear to me!?
I also don't use skelegons.
Btw, nice character!

hmmm... ok evenflow i'll have a butchers at your modded version.
basically, all the rigging was done thru following a book, but i had to modify it all to fit my character (the book was using a properly proportioned human) - its pretty annoying because i had it all fairly well sorted, or at least enough for me to begin doing a few tests - and its only this small problem thats getting in the way.
grrrr!
anyways...let me go check it out!
peace

Well if you just want to fix what you got as quickly and easily as possible, all you really need to do is rework the hierarchy. I made a quick screencapture. All I did was piece together some of the hierarchies that for some reason were broken apart. I'm also placed the goals right under the object itself. Otherwise the goals would be children of their respective pullers, which obviously won't work. Once this is done everything works, except the IK for the neck because it's IK chain isn't long enough.
I'll remove the video in a day or two, but do tell me when you've grabbed it.

EDIT:
Parent in Place was on all the time and when the mesh pops back into place at about 1:20, all I'm doing is executing Select All Bones of Current Object and then Record Bone Rest Position.

hey evenflcw
thanks for that dude! looks like that may well work a treat. a friend here at work sorted out the neck issue too so looks like i may be up and running...til i hit the next problem anyway.
my main trouble is a very short attention span you see..if something doesn't work i tend to give up
anyways..many thanks

"if something doesn't work i tend to give up"
I tend to do the opposite. Which I'm not sure is very good either. I've wasted alot of hours (even days) trying to do things that probably won't work in the first place or which would have gone alot faster had I bothered to learn stuff from the ground up instead of jumping straight in.
You're welcome!
