Jiggling of small objects

Support Particles and Physics Simulations

Hey guys,

I often have hard times to control the physics of smaller objects. They won’t stop jiggling or sometimes things look fine and suddenly the jiggling comes from nowhere. The objects I’m working with are rather small - some are below 1cm in size. The playing cards have a thickness of a mere 0,3mm.

I tried increasing the steps and solver iterations, used Convex Hull as well as Mesh and reduced the speed as well. Nothing really helped.

Maybe somebody can direct me towards a solution that will work for me in the future. That would be great.

Here’s a typical setup with a game board and 3 cards. The jiggling is clearly visible. Maybe you can find a solution based on this setup.

Thanks a lot,

Scale up would be my first advice. Failing that, I found subdividing / increasing mesh density alleviated some problems.

This goes through the effects of some variables.

Why make them real size ?
Scale the obejcts up and set the shape to mesh

Yeah - the scaling option is there of course. But wouldn’t it be nice to have an adjustment to increase precision for calculation while leaving everything at scale. After all, it’s just about relative values here, right.

If scaling up - is there something like a global scale setting or do I have to actually scale the object themselves?

Cheers,
Andreas
