In Blender I can do the following to check if an object has been transformed:

```
ident_matrix = Matrix.Identity(4)
obj_moved = obj.matrix_world != ident_matrix
```

I don't see any matrix identity functions in C4D.

Am I missing something?

If there isn't, what is the best way to check if an object has been transformed?

Thanks,

Chris

]]>This does what I wanted, and is the simplest answer:

```
obj.GetMg() == Matrix()
```

The function above could be used to check for a particular transformation, but it is overkill for this.

```
def CheckIdentity(op) :
matrix = op.GetMg()
if matrix.off == c4d.Vector(0,0,0) and \n matrix.v1 == c4d.Vector(1,0,0) and \n matrix.v2 == c4d.Vector(0,1,0) and \n matrix.v3 == c4d.Vector(0,0,1) :
return True
else:
return False
```

This does the trick.
