  • Shattered glass dynamic parts going through collider (floor) and non-stop jittering

    Hi all and happy new year!!

    Attached a scene I have created. I want to have the TV glass fall on the floor but you will notice part of the glass goes slightly through the floor. And some parts don’t stop jittering either. I have tried increasing substeps in project settings, changing custom mass, adding linear and angular damping, changing collision shape, bounce, friction and a ton others but nothing seems to solve either. Bits of glass still go through the floor and the smaller bits keep dancing like jumping beans.

    Any ideas what could I try or what am I missing?

    Thanks!

    ClothNurb is adding thickness but that is not included in the dynamics calculation so it can go right through the floor until the poly that *is* included finally contacts.
    Some of the jitter I think is caused by the construction, it would be better if you made the pieces and didn’t use a Fracture object to separate them (and then add thickness…) – it might help to cut the screen shape from the TV box as well rather than leaving it there, maybe not

    Amazing Brian, that’s exactly what I was looking for, many thanks!!

    I’ve recreated the scene you’ve done (first to practice what you have done) then only added dynamics to the centre pieces as I wanted to keep that hole only in the middle of the TV screen. Having the individual polys gives me way more control too.

    Here’s a still of the finished scene:
