Get prim's world transform via python?

[daviddeacon]

Hi,

I'm trying to get a stage primitives world transform using python so I can match a native Maya transform to the same position.

I'm struggling to achieve this, and can't find an answer while googling and sifting through the Usd API docs...

Any one know how this is achieved?

Cheers,
David.

Always the way, post the question then end up working it out myself. So will answer my own question for others to find.

from mayaUsd.lib import proxyAccessor as pa
import mayaUsd.lib as mayaUsdLib

from pxr import Usd, Sdf, UsdGeom
from mayaUsd import schemas as mayaUsdSchemas


import mayaUsd.ufe
import mayaUsd.lib
import ufe

def getPrimXForm():
    stagePath, sdfPath = pa.getSelectedDagAndPrim()
        
    print ("shapePath = "+stagePath)
    print ("sdfPath = "+sdfPath)
    
    stage = mayaUsdLib.GetPrim(stagePath).GetStage()
        
    primPath = Sdf.Path(sdfPath)
    print (primPath)

    prim = stage.GetPrimAtPath(primPath)
    Xformable = UsdGeom.Xformable(prim)

    xform = UsdGeom.XformCommonAPI(Xformable)
    t, r, s, p, z = xform.GetXformVectors(Usd.TimeCode.Default())
    print(t, r, s, p,z)
