Bug? Animated sculpture elements start to wander
I'm not sure where to put this, I hope this is fine.
Sooo, I made this creation: https://indreams.me/element/oCkavWRpMAg It's a multi element sculpture, linked by ball connectors and mainly animated with action recorders. Apparently, everything worked fine, even if you let the time run for longer. I submitted it to a community project and as it was put in, something odd happened: the connected elements started to wander slowly but consistently in one direction, taking the sculture apart over time.
I wanted to know what could caused this and tried around a bit. Turns out it has nothing to do with elements in den project scene it was put in, but the farther away from the scene center you put it, the more the elements start to wander. And there is nothing in the scene but the sculture, some paitings and the logic to animate it. I have no explanation what's going on. Maybe I'm missing something obvious, so please free me from this conundrum :D and maybe someone has an idea how to fix this while maintaining the animations?
Update: I think I fixed the problem, gave the connectors the possibility to maintain position by making parts moveable. If you want to have a view at the "buggy" version, choose the one from 3 of november, 12:16
Thanks for reading!

Well done on finding a fix! Yes, strange things start to happen regarding positioning if you get pretty far from the origin of the scene. This is because the numbers for positions get really large (eg. 1000000), which simultaneously means they cannot be so precise (eg. the difference between 0.00001 and 0.00002). So then it sort of rounds to nearby numbers, as precise it can get... but is never 100% correct.
This is actually happening all the time with numbers in computers, but when numbers aren't so big it's not noticeable.
So in this case, I'd try moving everything closer to the origin if possible.
Interesting making them movable helped though...
You can go to the versions and give a specific version its own version notes if you like--eg. mark that version as "buggy" so Mm can find it easily.
And you can report bugs at indreams.me/support so it goes straight into their system and such.

Thanks for clarifying. Makes sense to me, little numbers adding up seems to be the problem here, too. So, if this is a normal occurence, I wonder if it's even worth bothering Mm people to look into this?

In it's bugged state, the sculpture would have been practically useless, unless you put it in a maybe 3 to 4 meter radius around the center. I'm glad I found a solution for this.

I was wondering, too. If I understand it correctly, by making the connected parts moveable I gave it the means to "correct" the wrong small numbers in a physical way. That's mere speculation, I don't know much about the Dreams engine.
Thinking about it, if an element gets connected, it defauts to moveable. Maybe by turning it unmoveable and using it in an animation caused the problem in the first place. It still bugs me that the issue is not apparent if you build your sculture in the very center.

Oh, interesting.I didn't know it was possible to change the text after saving the version.

Yes, it's as if animation suffers from the problem, but connectors controlling the child object (because it's movable) doesn't somehow...

Interestingly I've found that my sculpts start to wander if I've used connectors to stretch them in any way. As soon as I animate the group, they start offsetting into infinite inside of the animated group. So I have to not use the stretch tool with the connectors to squish things.
