Ribbon Breaks Following Loop-D-Loop Curve Shape

[Atom]

I have a curve that loops back on itself. I have a shape following that curve.

When I emit a ribbon behind the shape it breaks whenever the shape travels through the top most portion of the curve loop.

I assume this is because some direction has changed inside the curve.

Is there anyway to fix this?

I want the ribbon to flow smoothly through the curve shape.

Hope it help you.

When moving object along a path , pay attention to the orientation of the up vector to avoid flipping issue.

What is the purpose of the null obj in your scene file ?

Thank you for taking a look at my file.

The purpose of the Null object is to contain the animation. I reference it's location for other objects that are following the same path. That way I don't have to make keyframes for every object that follows the path, they all just reference the Null for location.

 

So what was the change you made in the file?

At what node do I monitor the up vector?

I forget to put some notes in the file i post.

The up vector is accessible in the object  param at object level , below the motion path setting,

 i just set this vector to (1,0,0) as your null travel in the YZ plane.

Ah, makes sense. Thanks for the follow up information.
