Apple Motion - snap alignment to - bug?

Hey community.

im facing now a weird problem with the behavior “snap alignment to”

i have a basic circle shape. Nothing fancy.

and as a second object a star.

i use the motion path behavior with the snap alignment to behavior to make a simple animation. But instead of a smooth rotation of the star, it becomes now steps in the rotation. I’m not sure its a bug since the last motion update but I think it wasn’t like this before.

anyone out there with the same problem?

best regards

Marcel

Hi Marcel

Glad to hear we found a solution. To bring this to the attention of the Motion team at apple we should file a bug report.

Feedback - Motion - Apple

Please can you submit a report. I will do this too. (If anyone else see this thread and can reproduce the jittery motion path _snap alignment issue - please submit a report too)

Hi Nihilo

The youtube link is blocked as 'private'

There are a number of issues that can happen when using the motion path and snap alignment combination. Can you make the link accessible and provide a link to the project file in the youtube description? I can take a look for you.

Hey Rowie,

thanks for your message.

I changed the link to "not listet" now it supposed to work.

Link to Motionfile inside the YouTube link.

When I make a fast movement, it works - but if I have a slow movement, I have this stepping issue

Best regards

Hi Marcel

We can't put links in here, the moderator will remove it. Can you put the link in the youtube description section instead?

Anyway, I can see from the example the 'stepping' problem

I have set up a couple of basic motion path+snap alignment also, and I do see this problem too - and yes, i do not remember this happening recently. It is possibly a regression/bug from the last update.

Are you using 'geometry' as the motion path source? If so, change it to 'open spline' and create your path with that method instead. It seems to solve the problem for me. Also, in general - check the anchor points of the tree layer is correctly at the base.
