Motionbuilder Tip : Getting Global transformation values

Get transforms of testCube1, then Set those to testCube2 transforms…

cube = FBModelCube("testCube1")
position = FBVector3d()
rotation = FBVector3d()
scaling = FBVector3d()
cube.GetVector (position, FBModelTransformationType.kModelTranslation)
cube.GetVector (rotation, FBModelTransformationType.kModelRotation)
cube.GetVector (scaling, FBModelTransformationType.kModelScaling)

cube2 = FBModelCube("testCube2")
cube2.SetVector(position, FBModelTransformationType.kModelTranslation)
cube2.SetVector (rotation, FBModelTransformationType.kModelRotation)

cube = FBModelCube("testCube1")

position = FBVector3d()

rotation = FBVector3d()

scaling = FBVector3d()

cube.GetVector (position, FBModelTransformationType.kModelTranslation)

cube.GetVector (rotation, FBModelTransformationType.kModelRotation)

cube.GetVector (scaling, FBModelTransformationType.kModelScaling)

cube2 = FBModelCube("testCube2")

cube2.SetVector(position, FBModelTransformationType.kModelTranslation)

cube2.SetVector (rotation, FBModelTransformationType.kModelRotation)

Motionbuilder Tip: How to print out property fields

Simple code to print out the property fields of selected models…

from pyfbsdk import FBModelList, FBGetSelectedModels, FBPropertyManager

def PrintProperty( pModel ):
    lPropMgr = pModel.PropertyList
    for lProp in lPropMgr:
        print lProp.GetName()

lModelList = FBModelList()

# Get the selected models.
FBGetSelectedModels( lModelList )
for lModel in lModelList:
    PrintProperty(lModel)

# Cleanup.
del( lModelList, PrintProperty )
del(FBModelList, FBGetSelectedModels,FBPropertyManager)

from pyfbsdk import FBModelList, FBGetSelectedModels, FBPropertyManager

def PrintProperty( pModel ):

lPropMgr = pModel.PropertyList

for lProp in lPropMgr:

print lProp.GetName()

lModelList = FBModelList()

# Get the selected models.

FBGetSelectedModels( lModelList )

for lModel in lModelList:

PrintProperty(lModel)

# Cleanup.

del( lModelList, PrintProperty )

del(FBModelList, FBGetSelectedModels,FBPropertyManager)

Motionbuilder Tip: Get Current Filepath

Short and simple code to get current directory of open file…

lDstFileName = FBApplication().FBXFileName 
directoryPath = os.path.dirname(lDstFileName)
print directoryPath

lDstFileName = FBApplication().FBXFileName

directoryPath = os.path.dirname(lDstFileName)

print directoryPath

Been learning some Motionbuilder Python API

And let me tell you it is frustrating as hell…. something as simple as just trying to connect the Translate Y of one attribute to another is like an insane amount of code. It literally makes you want to throw a chair at someone. Here’s a nice example for that simple connection:

lConstraintRelation = FBConstraintRelation('Test')
lConstraintRelation.Active = True

A = FBModelNull('NullA')
A.Show= True

B = FBModelNull('NullB')
B.Show= True

sourceBox = lConstraintRelation.SetAsSource (A)
convertBoxV2N = lConstraintRelation.CreateFunctionBox('Converters', 'Vector to Number')
targetBox = lConstraintRelation.ConstrainObject (B)
convertBoxN2V = lConstraintRelation.CreateFunctionBox('Converters', 'Number to Vector')

#Link up the constraints, connecting Source Translation to converterBox Vector to Number first
#Then connecting convertBoxV2N to converterbox Number to Vector, then finally
#connecting just the Translate Y of converterBoxN2V to our Target Translate
OUT = FindAnimationNode (sourceBox.AnimationNodeOutGet(), 'Translation')
IN = FindAnimationNode (convertBoxV2N.AnimationNodeInGet(), 'V')
if OUT and IN:
print "Success1"
FBConnect(OUT, IN)

OUT = FindAnimationNode (convertBoxV2N.AnimationNodeOutGet(), 'Y')
IN = FindAnimationNode (convertBoxN2V.AnimationNodeInGet(), 'Y')
if OUT and IN:
print "Success2"
FBConnect(OUT, IN)

OUT = FindAnimationNode (convertBoxN2V.AnimationNodeOutGet(), 'Result')
IN = FindAnimationNode (targetBox.AnimationNodeInGet(), 'Translation')
if OUT and IN:
print "Success3"
FBConnect(OUT, IN)

lConstraintRelation = FBConstraintRelation('Test')

lConstraintRelation.Active = True

A = FBModelNull('NullA')

A.Show= True

B = FBModelNull('NullB')

B.Show= True

sourceBox = lConstraintRelation.SetAsSource (A)

convertBoxV2N = lConstraintRelation.CreateFunctionBox('Converters', 'Vector to Number')

targetBox = lConstraintRelation.ConstrainObject (B)

convertBoxN2V = lConstraintRelation.CreateFunctionBox('Converters', 'Number to Vector')

#Link up the constraints, connecting Source Translation to converterBox Vector to Number first

#Then connecting convertBoxV2N to converterbox Number to Vector, then finally

#connecting just the Translate Y of converterBoxN2V to our Target Translate

OUT = FindAnimationNode (sourceBox.AnimationNodeOutGet(), 'Translation')

IN = FindAnimationNode (convertBoxV2N.AnimationNodeInGet(), 'V')

if OUT and IN:

print "Success1"

FBConnect(OUT, IN)

OUT = FindAnimationNode (convertBoxV2N.AnimationNodeOutGet(), 'Y')

IN = FindAnimationNode (convertBoxN2V.AnimationNodeInGet(), 'Y')

if OUT and IN:

print "Success2"

FBConnect(OUT, IN)

OUT = FindAnimationNode (convertBoxN2V.AnimationNodeOutGet(), 'Result')

IN = FindAnimationNode (targetBox.AnimationNodeInGet(), 'Translation')

if OUT and IN:

print "Success3"

FBConnect(OUT, IN)

Hope […]
