Hi, I have created a geo node who's world transforms are matched to those of the current viewport, using the following Python. import toolutils viewer = toolutils.sceneViewer() viewport = viewer.curViewport() xform = viewport.viewTransform() obj = hou.node("/obj").createNode("geo") obj.setWorldTransform(xform) So far so good... Now I want to set these values with Python parameter expressions on the object so that the transforms are updated when the viewport is tumbled. The problem I'm facing is when I try to access the individual components of the xform matrix to set as the object parm I get "the Matrix4 object is not iterable"...??? Any ideas how I can dynamically link an objects transforms to those of the viewport? Thanks for any tips, WD
