Hi,everyone! I met a problem when making a motion path. So odd deformation occured to my object.

I need a nurbs run along a spiral . So I select my nurbsPlane and curve , and then use "Attach to motion path" ( I only tweaked the start/end time and front Axis ). Then I apply the "Flow path object" to my nurbs(tweak the divisions). I've done some animation like that without any issue. But, this time some odd deformation occured to my nurbsPlane at certain frame. I just don't know what's happened and how to fix it?

Any and all help will be greatly appreciated!

I find that when the nurbplane and path scale is some smaller value like 1/10 , the distortion did not happen that frequently.

Nobody met similar problems?

Thank you!
