I´m working on a Robot Animation based on a Mixamo-Rig. The Base-Body is rigged and a lot of additional Parts are attached by constraint expressions. Everything works as expected and renders nice & fast.
By finishing the Project I enabled object motion blur in the object-tag. Now the constraint objects are not updating, not moving with the rigged mesh.
I searched the Web & the forum. I rendered the animation starting at frame 0. I attached the object-tag to the meshes within the Null with the constraint Tag. Force Update is enabled. Nothing works

I´m using the OctaneRender_Studio_2020_2_RC5 and the latest Plugin Version 2020.1.5-R5
Can anybody help?
