When rendering physics with motion blur object turns in to a streak in a random direction

when rendering physics with motion blur, the physics object turns in to a streak in a random direction i dont know why

It’s a known bug in the Blender bug reports :slight_smile:

Would baking such physics to keyframes eliminate the issue?

no it still happens anyway

oh what should do in mean time?

are you referring to ticket T96391?
