Collision problems

Hello,

Im doing some fluid tests interacting with softbodys.
But im having some troubles with collisions, the particles are colliding
with the softbody until at a sertain point when the energy of the object deformation turns back/bounce up, then the particles just go trough the object, i tried different parameters for collision distance, turned on autocollision,etc. with no help. Here's a quick test demonstrating the problem. I used a simple sphere with a shell modifier to give it some thickness. Any solution for this problem?

Unfortunately I couldn't see the video, the browser hangs forever when clicking on it. In any case it would be better if you could post the scene so we can have a look at it. Please don't forget to include any object files you might have referenced.

Thank you very much.

Thank you very much for posting the scene. We are investigating the problem and I will post here again when we find the problem and the solution.

One thing that you could try If you don't mind is to increase the tessellation of your bag. My guts are telling me that could be the problem.

Again, thank you for reporting this problem.

This problem has been fixed (Bug #RF-45). Available in the next patch (coming out in July).

Thought so, even with denser mesh it doesnt work..

Thanks for the heads up;
