Python for maya - Renaming and Skinning Multiple joints

Johnm3D

ok so im creating this auto rigger, ive currently got it so it can create several joints each at its own object,I want to try and get it so it names the joints after the object it is created on and add _Joint to the end of its name.

Also as the title says, I want to add skinning, I cant get my head around it.

thanks for any help !

haiddasalami

For the naming, you already get the name from the for loop so you can just do something like

cmds.joint(p=piv[0:3], name="%s_joint" % (geo))

(The % is a quick way to concatenate strings in python). Not sure about the skinning.

Should have just bumped this one up than make a new thread haha.

Johnm3D

Thanks again :P yea i wasn't sure, I thought I should maybe make a new thread in-case someone else searches for something similar in a thread title.

Johnm3D

*bump* lol, OK so I have got what I need set up, I know how to parent the stuff. but when I put in the parent script underneath what I have already put, it states that it cant find the bones (because it hasn't made them yet) is there a way for me to delay its check for the joint within the same python script ? or will I have to set up a separate script to perform the parenting. If so, I have been attempting to create a GUI using buttons but cant figure out how to call a script when the button is pressed.

Thanks for any help !

John.

ps - these two websites are what I am going from to learn what to put into my script but some parts, im finding harder to figure out.

Mind posting the code? The parent stuff should probably go after the generation of the bones. Ideally you want to split the function of the scripts into well functions. The button would startoff a main procedure (something like autorigStart) which in turn calls helper functions like generating bones, parenting etc. Probably be able to help more once you post up your stuff.

Johnm3D

ok sure, here is my menu code so far

import maya.cmds as cmds

window = cmds.window( title="Long Name", iconName='Short Name', widthHeight=(200, 100));
cmds.frameLayout(lv=0, borderStyle='etchedIn');
cmds.columnLayout( adjustableColumn=True );
cmds.button( label='Help Me');
cmds.button( label='Close', command=('cmds.deleteUI(\"' + window + '\", window=True)') );
cmds.setParent( '..' );
cmds.showWindow( window );

and this is the rest

import maya.cmds as cmds



for geo in cmds.ls('RL_Wheel', 'RR_Wheel', 'FL_Wheel', 'FR_Wheel', 'Bonet', 'Chassis'):

    piv = cmds.xform(geo, q=True, piv=True, ws=True);
    cmds.select(clear=True);
    cmds.joint(p=piv[0:3], name="%s_joint" % (geo));

after this part i was looking at firstly parenting the joints to the chassis joint, then he joints to their relevant parts of the vehicle.

cmds.parentConstraint( 'Chassis_joint', 'RL_Wheel_joint' )

etc

haiddasalami

What you're looking for is cmds.parents not parentConstraint

so in

cmds.parent( 'pSphere2_joint', 'pSphere1_joint' )

pSphere2 will the child and pSphere1 joint will be the parent. Also should edit your window code to this:

if cmds.window('MyWindow', exists=True):
    cmds.deleteUI('MyWindow')
window = cmds.window("MyWindow",title="Long Name", iconName='Short Name', widthHeight=(200, 100));

That way you dont have multiple windows showing up.

Out of curiosity is this for a school project?

Johnm3D

Last question, fingers crossed.

when I first execute the script above that creates the joints at the pivots (this will be button 1 on my UI)

then I execute this script the bind the joints (button 2)

i get this error after executing the bind joints

# Error: RuntimeError: Not enough objects or values. #

this is the script I came upwith, I remembered that I used smooth bind when I created the original rig, after the rig is bound, I then parent bones to the chassis_bone

import maya.cmds as cmds

for geo in cmds.ls('RL_Wheel', 'RR_Wheel', 'FL_Wheel', 'FR_Wheel', 'RL_Door', 'RR_Door', 'FL_Door', 'FR_Door', 'RL_Suspension', 'RR_Suspension', 'FL_Suspension', 'FR_Suspension', 'Boot', 'Bonet', 'Chassis'):
    
    rootBone = "Chassis_joint"
    cmds.skinCluster("%s_joint" % (geo), "%s" % (geo),
        toSelectedBones=True,
        ignoreHierarchy=True,
        normalizeWeights=2,
        dropoffRate=0.1,
        removeUnusedInfluence=True,
        
    );
    cmds.parent("%s_joint" % (geo),rootBone);

for the UI do I put these two scripts in with the UI script then have the buttons execute them or do the scripts all have to be separate? if that makes sense.

Sorry if im asking alot of questions, I am currently reading the two websites I mentioned earlier as well as this book - Maya Python for Games and Film.

that book is helping me alot (for those who are learning python for Maya and reading this thread) hence why I have been able to come up with the bind skin script myself. I cant seem to figure out the error though. also any help with the menu is greatly appreciated, the menu seems more confusing then it should me.

thanks again,
john.

Johnm3D

ok so I figured out the error, it was because I was trying to connect Chassis_joint to itself.

I changed that by having a button in my menu change Chassis_joint to Root_Bone.

I have created a few buttons that function properly but there are two buttons which I can't get to work and thats because they are using a string I think its called ? here is the button -

cmds.button( label='Parent Bones', command=("cmds.parent('%s_joint' % (geo), 'Root_Bone' )") );

now I know for a fact that this bit of code works outside of the button, but I believe because the

% (geo)

is commented it gives me this error

# Error: Invalid Code Fragment: Found no executable Python code. #

now when I just put a single bone in the command button instead of the string like so

cmds.button( label='Parent Bones', command=("cmds.parent('RL_Wheel_joint', 'Root_Bone' )") );

it works perfectly for that single joint and creates the bone.

Basically, what i'm asking is, is there a way to get this working, I was thinking of perhaps naming it outside of the button to call it, if that makes sense eg

Bones = '%s_joint' % (geo);
cmds.button( label='Parent Bones', command=("cmds.parent('Bones', 'Root_Bone' )") );

but I know that doesn't work, I can't figure out how to set that up properly, if someone understands what i'm actually trying to achieve

Thanks in advance !!
John.

Hey John, sorry didnt see the bump. So reason why it doesnt work is because geo is a temp variable that is referenced in the for loop (You can call it later in the script too but it would be the last object in the selection list or objects passed in. What you want to do is seperate functionality into functions. This way you can call a command to the button using the command flag. Also note that maya likes to send arguments (none that we are using but maya uses) so we need to add *args to the arguments list for the function. Formatted your code as an example. There were parts missing from before so I just added them.

import maya.cmds as cmds

def createUI():
    if cmds.window('MyWindow', exists=True):
        cmds.deleteUI('MyWindow')
    window = cmds.window("MyWindow",title="Long Name", iconName='Short Name', widthHeight=(200, 100));
    cmds.frameLayout(lv=0, borderStyle='etchedIn');
    cmds.columnLayout( adjustableColumn=True );
    cmds.button( label='Help Me', command=createBones);
    cmds.button( label='Close', command=('cmds.deleteUI(\"' + window + '\", window=True)') );
    cmds.setParent( '..' );
    cmds.showWindow( window );

def createBones(*args):
    for geo in cmds.ls(cmds.ls(sl=True)):
    
        rootBone = "Chassis_joint"
        piv = cmds.xform(geo, q=True, piv=True, ws=True);
        cmds.select(clear=True);
        cmds.joint(p=piv[0:3], name="%s_joint" % (geo));
        cmds.skinCluster("%s_joint" % (geo), "%s" % (geo),
            toSelectedBones=True,
            ignoreHierarchy=True,
            normalizeWeights=2,
            dropoffRate=0.1,
            removeUnusedInfluence=True,
        
        );
        cmds.parent("%s_joint" % (geo),rootBone);
        
createUI()

Also another thing to watch out is that you do checks on say what you are selecting or if the rootbone exists etc.

Johnm3D

thank you ! that was exactly what I needed to finish all of my buttons ! the menu is actually completed if I could give you kudos on this forum I would ! one last small question, purely for aesthetics, can you change the state of another button once the one before it has been pushed, eg

button1 - enable=True
button2 - enable=False

when button 1 is pressed it changes button2's enable state to True

is this possible ? would help to stop people pressing the buttons in the wrong order and stuff

Yeah. You can use another built in module called partial from functools and send arguments to the function. You would have to do something like:

import maya.cmds as cmds
from functools import partial

def createUI():
    if cmds.window('MyWindow', exists=True):
        cmds.deleteUI('MyWindow')
    window = cmds.window("MyWindow",title="Long Name", iconName='Short Name', widthHeight=(200, 100));
    cmds.frameLayout(lv=0, borderStyle='etchedIn');
    cmds.columnLayout( adjustableColumn=True );
    #Declare all your buttons making sure to give assign them to variables   
    createBonesBtn = cmds.button( label='Click Me');
    secondBtn = cmds.button(label='I\'m disabled', en=False)
    cmds.button( label='Close', command=('cmds.deleteUI(\"' + window + '\", window=True)') );
    #Edit button commands here.    
    cmds.button(createBonesBtn, edit=True, c=partial(createBones,createBonesBtn,secondBtn))  
    cmds.button(secondBtn, edit=True, c=partial(secondButtonFunc,secondBtn,createBonesBtn))      
    cmds.setParent( '..' );
    cmds.showWindow( window );

def createBones(originalBtn,setActiveBtn,*args):
       
    for geo in cmds.ls(cmds.ls(sl=True)):
    
        rootBone = "Chassis_joint"
        piv = cmds.xform(geo, q=True, piv=True, ws=True);
        cmds.select(clear=True);
        cmds.joint(p=piv[0:3], name="%s_joint" % (geo));
        cmds.skinCluster("%s_joint" % (geo), "%s" % (geo),
            toSelectedBones=True,
            ignoreHierarchy=True,
            normalizeWeights=2,
            dropoffRate=0.1,
            removeUnusedInfluence=True,
        
        );
        cmds.parent("%s_joint" % (geo),rootBone);   
    #Doing our toggle here
    cmds.button(originalBtn, edit=True, en=False, label='I\'m disabled')
    cmds.button(setActiveBtn, edit=True, en=True, label='Its alive')  

def secondButtonFunc(originalBtn,setActiveBtn,*args): 
    #Doing our second button toggle here  
    cmds.button(originalBtn, edit=True, en=False, label='I\'m disabled')
    cmds.button(setActiveBtn, edit=True, en=True, label='I\'m back') 

createUI()

Hey, ive been having feedback from the script, and have found that the export function doesn't work because it can't create the temp folder in the C drive on some peoples computers.

This is what I was using.

import maya.cmds as cmds
import maya.mel as mel
from functools import partial

def exportVehicle(originalBtn, setActiveBtn, *args):

        cmds.headsUpMessage( 'Exporting your Vehicle...!', time=5.0 )
        mel.eval('FBXExport -f "C:/Temp/MyVehicle.fbx";')
        cmds.button(originalBtn, edit=True, en=False, bgc=[0,1,0])
        cmds.button(setActiveBtn, edit=True, en=True, bgc=[0,0,0])            
        cmds.headsUpMessage( 'Vehicle has been Exported to "C:/Temp/MyVehicle.fbx", You may now Close...!', time=5.0 )

What I have been trying to find out is if maybe I could create some sort of string in the address maybe? i'm not sure if thats the right way to go about it. What I need to do is maybe send the exported file to the users "my documents" or maybe just the desktop. but I can't seem to achieve this because of the users computer obviously has different user name which changes the address.

Just wondered if you could point me in the right direction ( thats if im making any sense :P )

Thanks

Johnm3D

Just bumping, just incase the edit doesn't bump it for me.

I also wondered if I could put a text field so the user could type / copy and paste their desired save location and then it reads that texts and inputs that string into the -f flag string? if the previous method isn't doable perhaps this method is ?

haiddasalami

You could use the fileBrowserDialog2 command linked to a button to get a directory picker. Then just add a textfield and edit that. To get the user profile use the os module

import os

userhome = os.path.expanduser('~')

That should return DriveLetter:\Users\Username

Johnm3D

Ok so I get most of what you said, this is what I have done so you know where I am -

def exportVehicle(originalBtn, setActiveBtn, *args):

        cmds.headsUpMessage( 'Exporting your Vehicle...!', time=5.0 )
        cmds.fileDialog2(fileMode=2, caption="Export Vehicle")
        #mel.eval('FBXExport -f "C:/temp/MyVehicle.fbx";')
        cmds.button(originalBtn, edit=True, en=False, bgc=[0,1,0])
        cmds.button(setActiveBtn, edit=True, en=True, bgc=[0,0,0])            
        cmds.headsUpMessage( 'Vehicle has been Exported, You may now Close...!', time=5.0 )

the commented out mel.eval was what I was running before.
I just don't understand what you mean by the textfield and the os module. cant find what I need in the maya python commands page so im guessing its from a different library or something like the functools ?

Thanks.

Johnm3D

Sorry I was tired last night and couldnt figure it out, woke up this morning and tried somthing durastic. took away the folder names and waited to see where it saves, and it goes to desktop. Just waiting for people to confirm this works on their computers.

#new
mel.eval('FBXExport -f "MyVehicle";')

#old
mel.eval('FBXExport -f "C:/temp/MyVehicle.fbx";')

haiddasalami

Heres some sample code for you and how to use the path returned from filedialog.

import maya.cmds as cmds
import maya.mel as mel
import os

def createUI():
    if cmds.window('MyWindow', exists=True):
        cmds.deleteUI('MyWindow')
    window = cmds.window("MyWindow",title="Long Name", iconName='Short Name', widthHeight=(200, 100));
    cmds.frameLayout(lv=0, borderStyle='etchedIn');
    createBonesBtn = cmds.button( label='Export', command=exportVehicle);
    cmds.setParent( '..' );
    cmds.showWindow( window );
    
def exportVehicle(*args):
    cmds.headsUpMessage( 'Exporting your Vehicle...!', time=5.0 )
    path = cmds.fileDialog2(fileMode=0, caption="Export Vehicle", fileFilter="*.fbx")
    mel.eval('FBXExport -f "%s" -s'%(path[0]))
    cmds.headsUpMessage( 'Vehicle has been Exported to %s, You may now Close...!' % (path[0]), time=5.0 )
createUI()

The os Module is like functools where its a built in module for python. Using the command userhome = os.path.expanduser('~') would give us their user folder so for Windows it would be like C :\Users\Username and then you can appent whatever folder you want so if you wanted Desktop you could do userhome + "\Desktop" and there you go. Will export out to desktop. I would highly suggest doing either option as this makes your export process foolproof.

Johnm3D

Hey, hopefully you will see this, I finished my Uni course and wanted to carry this on as its good for my portfolio as well as me finding it highly enjoyable. Im trying to do the whole UI now. Basically what I want is this (very basic diagram :P ) - This img


Basically, I want a box for the root_bone to be inserted into by the user having the object selected and then hitting a button next to the non editable text box where the name of the object will appear. then a similar thing will occur for the child bones except I wanted there to be a + button to add more boxes for children, as well as another button to add a child bone to the children for stuff like turrets, the names that will be added to this text box, I want to be added to the selected list (cmds.ls ('blah') ) which will then be rigged.

Ive figured out how to add more textboxes but not sure how to make these boxes none editable, also they get added onto the end of my script, but I want them to be added to a specific place, before the rigging buttons.

hopefully this makes sense, this is the add text box script that ive figured out -

    cmds.textField( editable=False );

    cmds.button( label='Add Object', command=('cmds.textField(parent=\"' + parentLayout + '\"); ') );
    cmds.setParent( '..' );

ive been looking on the autodesk and python documentation but cant seem to find how to add a selected objects name into the box by a click of a button.

im guessing im going to need some kind of string to get the object names from the box's to the selected list, this is the part that confuses me the most, strings are my weak point atm

Johnm3D

hmmm, bump? :P Just really want to get the most of this and make it a great tool for the community to use any help is great, its come along way since last post.

haiddasalami

Hey sorry Johnm didnt see this before but you mind posting the code you already have? Just having a bit of trouble understanding the function of the ui.

Hey Johnm sorry for the late reply heres some code to get you started. I think you should start moving stuff into functions as its better than formatting everything into a string.

I edited your add button command to:

cmds.button( label='Add Object', command=partial(addObject,parentLayout ) );

and the function is

def addObject (parentLayout,*args):
    selection = cmds.ls(sl=True)
    if len(selection)>0:    
        cmds.textField(parent=parentLayout,editable=False,text=selection[0])

I dont think this is the right approach to this and maybe something like a treeView ()http://download.autodesk.com/us/maya/2010help/CommandsPython/treeView.html) might help though I dont have much experience using it. When I get some time I'll try and something quick for you.

Hey guys im really glad i found this post, Can you guys recommend me a place i know a little bit of python already, i would like to eventually move on to automating my rigging with autorigs, UI's and such, where is a good place to start learning how to make rigging and OOP tools in maya?

Best.
Joe

Hey, sorry I didn't see your post. I used a mixture of Python and Maya Documentation along side asking for help on this forum. If you have money id recommend tutorials as well, I haven't been able to as of yet.

@rabbijoe, ya maya docs, but if your wanting to use it for rigging and wanting to learn OOP concepts you should move to pymel, and stop using maya.cmds, it is mostly all oop.
