Re: [Maya-Python] MMeshIntersector: Getting world position / matrix of point in object space
You should at least pass the identity matrix like this meshIntersect.create(mesh, om2.MMatrix.identity) -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.

Re: [Maya-Python] MMeshIntersector: Getting world position / matrix of point in object space
Hi, as for the missing Matrix parameter, there is this thread: https://groups.google.com/forum/#!topic/python_inside_maya/axX7W8imeEU I have the same problems as described there, if I pass the matrix I will get this error: More keyword list entries (4) than format specifiers (2) But you are right, there has to be a Matrix parameter as the documentation says:. then the matrix passed to create() should provide the mapping from world space to the mesh's object space.

[Maya-Python] Catching maya's error ?
hello,
i have a code where i am using try and except
ex:
try:
do_something()
except:
cmds.warning("some error")
function may give some error ex: "pCube03 not found", "can't constraint
pCube02"
how can we catch that error message and use that in except as warning.
