Can't get back to bindpose. How to add influence joints?

[fortner]

just delete it.

[Nenox]

I tried selecting all joints and running this command:

dagPose -q -bindPose;

It returned: bindpose6

I typed: delete bindPose6.

Now i get the message No bind pose when i do: go to bind pose.

Cool - but..

Still, when I add an influence, as soon as I assign weight to that influence the verts move to where the mesh originaly was bound. (I can see this by turning off the skinCluster).

So that did not work. Unless I did something wrong??
Thanks.

[Nenox]

OK. Here's where I'm at.

Deleting my bindPose or reseting it, like I had allready tried, alows me to add influences. That's a step in the right direction. :)

Came up with a hack.. :scream: After doing one of the above, I was able to match the position where the mesh was bound initialy. (by turning my skinclusters influence up and down and then tweaking my skeletons rotations to match the unbound pose as closely as I needed.) This will work for my current needs.

Still it would be nice to hear if there is indeed a "propper" way around my problem.


Cheers.


p.s. Finaly starting to include mel in my posts... I feel all grown up now! :wise:

check out the -ibp/ignoreBindPose flag in the help on the "skinCluster" command.

you can add an influence when NOT in bindPose AND keep the bindPose...

Nice one John.

I tried this:

skinCluster -e -lw true -wt 0 -ibp -ai L_Clavicle skinCluster2;

I worked just fine. I still had the problem of the verts going to the place of the original bind when weighting them to the new joint, but I guess that was not the point of using the -ibp flag.

Cheers.

[john_homer]

oh, OK, didn't realise that....

I would just delete it...
or..have you tried just turning off all the IK etc (with modify->evaluate nodes->...)
and then, got to bindPose?

.j

[Nenox]

Yeah. I made sure I unlocked all transforms and turned evaluation of approiate node types off, but no go..


B.t.w.: Was the point of using -ibp flag:

-To be able to add influences while not at bindpose.
-To be able to add influences while not at bindpose and avoid the problems of verts jumping back to the bindpose when weight is added to the influence.
- Something different entirely ;)

Sorry, I just wan't to be sure I understand You correctely.


Thanks a bunch.


p.s. Just made a little script here for locking all influence weights of a selected skinCluster:

string $skinClusterName[];

$skinCluster = `ls -sl`;

string $influenses[];

$influences = `skinCluster -q -wi $skinCluster`;

for($i in $influences)

{

setAttr ($i + ".liw") 1;

};

(Works in reverse by changing 1 to 0 ;) )

I agree with homer----I would NEVER delete it .... this is all you have to do .. Go to Modify>EvaluteNodes> Ignore ALL(this will turn off your ik,expressions,and constraints.) Then go to Edit>Select By ALL Type> Joints. Now go to Skin>Go to Bind Pose... Now you can add all the influences you want. Just make sure after you add all of them,You go back to Modify>EvaluteNodes> and turn on Evaluate ALL...... If you like the mel for it here it is make it to easy buttons.....


on (file:///on) button (to make you able to get to bindpose )
--------------------------------------------------
DisableAll;
select -r `ls -type joint`;
GoToBindPose;
--------------------------------------------------


off (file:///off) button (after you add what you need ,to get things back to normal)
--------------------------------------------------
EnableAll;

--------------------------------------------------

Hope this helps

you can't always get back to bind pose by turning off evaluation of nodes. I've never had any problems deleting a bind pose at all, and I've done it like crazy on countless characters on a number of productions. It's fast, you don't have to trouble shoot, and it's never done anything harmful to any of my characters.

I have never seen a rig that i could not get back to the bindpose.(and i to have been alot of rigs ) By doing that cause it turns off all connections to the joint.( ik,expressions,and constraints) (your back to basic rotate of the joint) But if you saying that you have seen a rig, That would not get back to it would not supprise me. ( dam Maya made by humans) hahaha

[john_homer]

I'm with Mike,
I've been deleting the little buggers for years...
and have had lotsa cases where maya fails to achieve bindPose, even with evaluate all OFF..

hi Nenox,
not that I'm trying to show you up... ;)
but I have a script similar to yours, but you just select the surface... rather than the skinCluster...
also it forces the component editor to updaye.. cos its not to flash at that...
same as your for setting ON or OFF... first line...
here 'tis

// ON OR OFF
int $val = 1;

// GET THE JOINTS IN THE SKIN CLUSTER
// ON THE SELECTED OBJECT
string $sel[] = `ls -sl`;
string $history[] = `listHistory $sel[0]`;
string $clusterName[] = `ls -type skinCluster $history`;
string $infs[] = `skinCluster -q -inf $clusterName[0]`;

for ($current in $infs)
{
setAttr ($current + ".liw") $val;
}
// UPDATE COMPONENT EDITOR
compEdMenuCmd CEMIAutoUpdate componentEditorPanel1WindowComponEditor;

[zeroeefx]

Its just a place holder not saying you can't delete it , but if i can keep my first one i will :)

[Nenox]

Thanks a lot for your time guys!

- Ken:

Evaluate>ignore all + unlocking joint transforms was done before posting the thread. I did however neglect to unlock non joint transforms in the skeleton hierarchy. :blush: Now I can indeed get to bindPose. The only funny thing is that even though I can all influences, and the verts don't move when I apply weight to them, the mesh still moves quite a bit away from the joints when i turn my skinCluster off.. Thanks.

- John:

Funny!

"you just select the surface... rather than the skinCluster..."

I was trying to find a way to do just that myself! :) I didn't suceed and I'm afraid I'm not quite sure why your code works and I failed misserably! :cry: Anyway, thanks for sharing!!

B.t.w. The mel i posted was not really intended to enlighten you, but more for someone less knowing (like me) readning along.

One last thing. I did find that i have to kill my character sets before i can add the influences without any trouble. The mess starts as soon as i grabb the timeline, and verts start flying off into space. This is when adding joints that have been in the skeleton hierarchy all along, but have not been part of the skinning. When createing a brand new joint, I must also kill all the connections from my animcurves to avoid this issue. Beats be.. ?!?

Thank again,
Sune
