Ok, if the card is coming in with transforms then you could add a
transform node directly after this that negates the transforms and puts
it back at 0,0,0. You can then add a transform node to do whatever you
want based on the local axis and then a third transform node to put it
back to the original position but with your additional transform.
Essentially the first and last step are your 'freeze transform' and the
transform in the middle are the values you would add had you zeroed out
all the x,y,z and rotation values as in Maya, essentially in local space.
Seems long winded but these scenarios crop up all the time.

Well. Maybe I'm not getting the hang of it.
But because each transform adds to the transformations it can get
harder to animate.
Lets say I got an fbx from the 3d department.
It has a card that sits where it should and its rotated 37.8337 on the
z away from the camera. And I want to animate it so the z axis is
facing the camera. Since the way it is now if I move it to the camera
I need to move it on z and x together and that makes is hard to
control the curves.
Hope I got my point through

Not really sure why you need this? The joy of a node based
workflow is that you don't need to do things like freeze
transforms. Simply add another transform or axis node.
Your card is translated and rotated away from 0,0,0. if you want
to move this further or rotate a specific amount relative to this,
just add another Translate between the object and the current
transform. For this reason I very rarely do transforms in the
actual geo transform knobs. As long as you put the transform
nodes in the correct order you won't have problems with things
rotating around 0,0,0.

How should a write geo do it?
A write geo will write the object again.
I wondered if there's an easy way to freeze the transformation.
Lets say I have a card at 2.3,1,4
And it's rotations are 12.32 , 18 , 180.
I want it to stay in the same place but the transformations to
reset to 0,0,0,
Can I do this with the write geo without having to export an fbx?
Sorry for the noob questions :)

*Subject:* [Nuke-users] Freeze transformation in nuke
Hey all.
One thing I can't get my head around.
In 3d programs u have the option to freeze/delete history if
a transformation so u can animate things more easily.
In nuke the use of axis or transformGeo nodes is a pain since
u have have to connect your nodes from 0,0,0 of the world.
Is there a script or a simple way to achieve it in nuke?
Thanks all.
