Topic Description
Prim orientation doesn’t match WritePrimAttribute value
Detailed Description
Hi, I would like to update an object’s prim pose with the WritePrimAttribute Node from Action Graph. I noticed that the translations are set properly, but orientations are incorrect.
Steps to Reproduce
-
Create a cube with orientation attribute
-
create an action graph with the nodes and connectivity shown in figure
-
set some const quaternion values
-
set the write prim attribute node values “prims” and “attribute”, optionally “attribute Type” quatd or quatf, (won’t make a difference to the result here), notice that the value in this node is correctly set by the const quaternion node.
-
play the simulation and check the orientation, quaternion values of the target prim. They are very off. And I don’t see the cube rotating when I change the const quaternion node values.
-
the euler angle values are somewhat close to the x, y, z value for the quaternion, but they don’t see to match the actual rotation.

Additional Information
What I’ve Tried
A workaround is to delete the orient attribute and add rotation, write prim attribute handle the euler angles correctly. But as described in the post Use Rotate in transform and not Orient , the rotation will be converted to orientation attribute when playing the simulation (for object with physics attribute rigid body with collider preset).
