Hi

that's several times now that I'm confronted with this issue, massive loss of volume, when trying to have some moving colliders interact with with my flip sim.

I tried increasing substeps, upping the resolution to ridiculously high values, tried different scales, diferent setup for my colliders nothing seems to fix the problem.

One of you guys have been experiencing the same trouble and found out a solution? I'd be delighted to hearing about a solution?

Thanks in advance

PS. here is a hipnc made at home but I need to resolve this issue at work on a real job.

Thanks again

If you search flip volume loss, you will see that it is a common issue, with or without moving colliders. In addition to volume loss, you will also have velocity loss, unless something pumps extra volume and velocity into the system. For a quick solution to your problem, reduce the grid scale on the flip object from 2 to 1. Your sim will be longer if you do this. For a lengthier explanation as to what is happening, take this link.

Thanks Midasssilver. Will give it a try today.
