Short description of error
When you change the number of motion blur steps more than 1 for camera, it starts to work incorrectly
Cycles 1 steps
Cycles 3 steps
Cycles 8 steps
Luxcore renderer 50 steps (in luxcore number of steps does not multiply, therefore such a large number)
Luxcore result looks much more accurate to me.
I also found some strange problem when I made camera object parent of 3D text, but I will talk about it later if necessary.
