bug: if you modify the vertices of an object and then copy them or undo a transform, the vertices will explode in different directions.
Repro steps:
1. Open Nuke
2. Add a ReadGeo node
3. Read in a .abc file with geo. The one the customer submitted and I tested with is available at the link in second comment-
(see path to .abc on share)
4. Read in 'all in one node'
5. View the ReadGeo node and frame in, in the viewer
6. Add an EditGeo node
7. Select vertices in the viewer and drag out
8. Repeat step 7 on a different part of the object
9. Try to undo step 8
Result: vertices edited in step 7 will have changed positions
This affect can also be achieved by creating multiple edit nodes each with vertex transforms and then copying these edit nodes and attaching them to a new readGeo node reading in the same file.
