Render instances and Motion blur randomly change the position of the instances

[LeSill]

Hi guys,

I had an imported STP model with several parts, including INSTANCES set to RENDER INSTANCE. When I activate MOTION BLUR in the options, some (or all) of the instances appear in the VFB render at random positions. When I set the instance mode of the INSTANCES to INSTANCE, the objects remained in their correct places.

Kind regards

I have similar issues with motion blur of objects. Usually IR works fine, but final render is totally scr*** with strange artefacts allover.
Best,

Image, specs, clear description, steps to reproduce and a test scene, ...  or it didn't happen.
