Hey Gal,
The empty is the parent to the cube children,
The children follow the parent wherever the parent goes.
So the empty (parent) is moving (sliding) along the curve, as the follow path constraint intends, and the 6 cubelets follow along.
It looks to me as if everything is working as it should be. When You render your animation, objects such as empties are not visible.
If it is a distraction in the viewport, you can hide the empty in the outliner.
I usually put any utility objects such as empties in a UTILS collection and hide the collection.
Hi Gal,
It goes really fast in your video, but I think I see what you mean by sliding. But I cannot troubleshoot from just that video. Maybe it's a problem with your Driver, a mistake in the Expression, or an interpolation issue...in extreme cases, it might be due to rounding errors...It's probably something else, but without seeing your file, I have no idea.
Hello Adrian and Martin ! Thank you for your answers in despite of my not so clear explanation.
The video is just a quick viewport render to see and explain the sliding issue along the time, such as comparing the start and the end.
I check the driver expression many times... There's no keyframe too...
If someone have the time and the will to check my file, I put it on my dropbox
Thank you
