Perhaps this is what you're looking for? worldMatrices = [xform(mesh.getParent(), q=1, worldSpace=1, matrix=1) for mesh in ls(type='mesh', ap=1)]
...or, you can also query individual components of the transform - translation, rotation, etc. - using the xform command. However, unless I'm misreading your question, I think you have a misconception of the way instancing works in Maya. In maya, an instance is simply any object with more than one DAG parent... so there is no 'master' and 'instance', they're both just instances: two different DAG hierarchy paths to the same object. Also, their transform nodes WOULDN'T (or at least, wouldn't have to be) the same... in most cases, they aren't. This also means that the way you'd go about getting world-space transformation info for an instance (once you have a dag path) is exactly the same as it would be for any other object. - Paul On Tue, Mar 24, 2009 at 7:11 PM, Justin Ball <[email protected]> wrote: > > I am still trying to get the best setup running with version 0.9.0 > with the script editor bug. > > I was using the line ls(type='mesh', ap=1) > > and yes I get all the meshes... but I need their transform information. > > and if I have instanced meshs, I am getting just the translation > information from the transform node. with is the same for both the > master and the instance since their transform nodes are the same. > > So I was wanting to use the function isInstanced() to tell me if a > mesh is instanced and could then get the world transform information > for the transform node and then add that to the transform information. > > I am assuming that is right?
