Hi!

I have an issue with a RBD shatter animation that I am trying to solve with no luck.

I shatter the glass on impact but pretty much every single crack flickers through the animation which is something I don't want of course. I have tried RBD Connected Faces / Disconnect but that removes the connected sides, thus removing the cracks which is something I also don't want.

Any ideas how to solve this would be greatly appreciated!

Cropped render attached (play it looped )

Thank you!

Hey did you ever find the solution to this problem? im currently experiencing the same issue

If a piece goes in and out of the other pieces around it, it will cause this sort of problem with refractions. You need to make 1000% sure those pieces are not moving.

IIRC there is a render setting to handle tolerances between transparent objects, usually for wet layers in eyes. Ray Bias perhaps?
